Loudest band

Last updated

The loudest band in the world is a subject of some dispute in musical circles. Many bands have claimed to be the loudest, measuring this in various ways including with decibel meters at concerts and by engineering analysis of the CDs on which their albums are published. The Guinness World Records no longer celebrates "The Loudest Band in the World" for fear of promoting hearing loss. [1]

By observation and reputation

Some bands have at times been described as extraordinarily loud by subjective opinion of reviewers, but not by actual measured decibel levels.

19th century

Volume in classical music is determined to some degree by the score, rather than the ensemble. However, many of the loudest performances have been determined by the size, instrumentation, inclination, and location of the orchestra, assuming a piece which is written to be loud.

One hundred musicians played at the 1813 premiere of Beethoven's work Wellington's Victory , which Corinna da Fonseca-Wollheim described as a "sonic assault on the listener" and the "beginning of a musical arms race for ever louder... symphonic performance", quoting an unnamed attendee as remarking that the performance was "seemingly designed to make the listener as deaf as its composer". Frédéric Döhl described performances of this work as "not like an evening at the Berlin Philharmonie, but rather like a modern-day rock concert". According to da Fonseca-Wollheim, music continued to grow louder after this as the world grew louder, partly due to developments in instrumentation (steel strings, metal flutes, valves on trumpets). [2]

The opening day of the 1869 National Peace Jubilee in Boston featured a performance of the Anvil Chorus that featured thousands of musicians, including 50 firemen pounding anvils as well as cannon and church bells. [3]

Performance of the 1812 Overture by the United States Army Band, 2008

Tchaikovsky's 1880 work 1812 Overture , which is scored for artillery and has passages marked as ffff (in a score, "fortississimo" (fff) instructs the musicians to play the marked passage extremely loudly and is normally the loudest volume specified; "fortissississimo" (ffff), which means to play louder than fortississimo, is sometimes used) has been described as the loudest classical piece. [4] [5] The piece has been played with FH70 155 mm (6.1 in) howitzers and Type 74 Main Battle Tanks included in the orchestra instrumentation [6] (a typical 155mm howitzer generates about 180 dB at the source, [7] [8] sufficient to sometimes cause immediate and permanent hearing damage (artillery crews are issued hearing protection)). [9] The piece is usually performed outdoors or with simulated or recorded cannons, but an indoor performance with live cannon at the Royal Albert Hall has been cited as having been particularly loud. [10]

Early 20th century

Pluck the string so hard that it hits the wood.

Gustav Mahler, instruction in the score of Symphony No. 7 (1904–05), which includes an fffff passage, albeit for strings rather than brass [11]

The "Mars" movement of Gustav Holst's 1918 work The Planets includes ffff passages. [12] The close of the finale of the 1919 suite of Stravinsky's 1910 work The Firebird is scored at ffff, [13] as are passages of other works.

According to James R. Oestreich (writing in 2004), modern symphony orchestras can easily reach 96 to 98 decibels, and certain brass and percussion instruments have registered 130 to 140 at close range. [14]

1948

Kids are going haywire over the sheer noise of this band... There is a danger of an entire generation growing up with the idea that jazz and the atom bomb are essentially the same natural phenomenon.

Barry Ulanov, Metronome , 1948 [15]

Stan Kenton's bands have been described as "the loudest of the big bands" [16] with "the shattering effect of the Kenton band's loud, dissonant brass" [17] created by "screaming 'walls of brass'". [18]

Bill Gottlieb wrote "Warm or cold, it was loud. Stan's screaming horns presaged the high decibels of the rock age, but his stalwarts did it without electronic amplification. Just old-fashioned lung power. When Stan raised his long arms to call for 'more,' the men in the brass section blew until their faces reddened, their eyes bulged, and incipient hernias popped." [17]

1968

Tiny articles in early rock magazines said Blue Cheer were so loud they had to record outdoors — part of their second album, Outsideinside, was recorded on a San Francisco pier

Neil Peart, Rolling Stone [19]

Blue Cheer, the first American band to use Marshall amps, [20] has been seen as a pioneer of extreme loudness, being the first band ever listed in The Guinness Book of World Records as loudest band in the world, preceding Deep Purple.[ citation needed ]

They have been described as "undoubtedly the heaviest and loudest band of the time", [20] "Weird, obnoxious, loud as in L-O-U-D!!!" [21] and "loud enough to get [god of music] Apollo's attention". [22]

Billy Altman described them as the loudest band ever; "So loud, in fact, that within just a few songs, much of the crowd [at a 1968 concert] in the front orchestra section was fleeing". [23]

Blue Cheer's 1968 debut album, Vincebus Eruptum, was widely described as the loudest record ever made at that time. [24] Their 1986 "Best of" compilation album was titled Louder Than God. [25]

1969

Daniel Kreps of Rolling Stone has maintained that "Whole Lotta Love" established Led Zeppelin's reputation as one of the loudest bands of their time. [26]

By decibel record

Decibel measurement is highly dependent on distance from the source of the sound; if this is not given, the sound level reported is of limited use. Also, sound level may be metered on several ways: average, maximum level (with the sound level meter set to Fast, Slow, Impulse, or Peak), etc. In addition, there are several decibel scales. Therefore, the decibels on the following list are not necessarily comparable to each other.

1972

Deep Purple Mark II in 1971 Deep Purple (1971).JPG
Deep Purple Mark II in 1971

Deep Purple was recognised by The Guinness Book of World Records as the "globe's loudest band" for a concert at the London Rainbow Theatre, during which the sound reached 117 dB and three members of the audience fell unconscious. [27] [28]

1976

The Who were next to be listed as the "record holder" at 126 dB, having been measured 32 metres (105 feet) from the speakers during a concert in London at The Valley on 31 May 1976. [29]

1984 and 1994

Manowar in 2016 Manowar 2016.jpg
Manowar in 2016

The Guinness Book of World Records listed Manowar as the loudest band for a performance in 1984. The band claimed a louder measurement of 129.5 dB in 1994 at Hanover, [30] but Guinness did not recognise it, having discontinued the category by that time for fear of encouraging hearing damage. [31] [32] [33] [34] [35]

1986

An article by Scott Cohen appeared in February 1986 issue of Spin entitled "Motörhead is the Loudest Band on Earth". [36] In it, Cohen alluded to an undated concert during which Cleveland's Variety Theater actually sustained damage from Motörhead reaching a decibel level of 130. [36] This he reported was 10 decibels louder than the record set by The Who. [36]

1990

The 1990 edition of the Guinness World Records contained the following entry: Largest PA system: On August 20, 1988, at the Castle Donington "Monsters of Rock" Festival a total of 360 Turbosound cabinets offering a potential 523 kW of programme power, formed the largest front-of-house PA. The average Sound Pressure Level at the mixing tower was 118 dB, peaking at a maximum of 124 dB during Iron Maiden's set. It took five days to set up the system."

1996

The English House/Electronica band Leftfield, while on tour to support their debut album Leftism , gained notoriety for the sheer volume of their live shows. In June 1996, while the group was playing at Brixton Academy, the sound system caused dust and plaster to fall from the roof, with the sound volume reaching 135 dB. [37]

2007

British punk band Gallows allegedly broke Manowar's penultimate record, claiming to have reached 132.5 dB; however, this record claim was made in an isolated studio as opposed to a live environment. [38]

2008

Manowar registered an SPL of 139 dB during the sound check (not the actual performance) at the Magic Circle Fest in 2008. [39]

2009

On July 15, at a Canadian concert in Ottawa, the band Kiss recorded an SPL of 136 dB measured during their live performance. Noise complaints from residents in the area eventually forced the band to turn the volume down. [40] [lower-alpha 1]

Deafening sound

Loud sounds have long been known to cause damage to ears. In Norway, this fact was proved for coppersmiths as far back as 1731. [44] Acoustic instruments may represent a risk for hearing damage, especially with lengthy exercising in rooms with high reverberation. [45] With powerful amplifiers and loudspeakers, the sound level and risk are increased. The volume at some concerts is above the level which may cause hearing damage without ear protection. A volume of 115  dB(A) risks permanent damage after only 30 seconds; [46] in the UK, Norway, and possibly certain other countries, exposure to sound at that level without ear protection for more than a few minutes is strictly prohibited. The sound level claimed at some of Manowar's performances may cause ear damage almost immediately; the phrase deafening sound should be taken literally. The Control of Noise at Work Regulations 2005 introduced safety limits for daily noise exposure in the UK, an average of 92 dB(A) over 30 minutes. [47]

Parodies

The notion of "loudness equals greatness" pervades rock music to the extent that it has been satirized. In the mockumentary This Is Spinal Tap , the band is presented by the fictional filmmaker Marty di Bergi as "one of England's loudest bands". One popular joke from the film features Nigel Tufnel displaying the band's amplifiers which are calibrated up to 11, instead of up to 10, allowing them to go "one louder". As a consequence of this, manufacturers began making amplifiers with knobs that went up to 11, or even higher, with Eddie Van Halen reputedly being the first to purchase one. [48] Marshall, the company that provided amplifiers for the film that the custom marked knobs were applied to, now sells amplifiers such as its JCM900 (first sold in 1990) whose knobs are marked from 0 to 20. [48] [49]

The fictional band Disaster Area (appearing in Douglas Adams's The Restaurant at the End of the Universe ) plays concerts which can literally devastate entire planets. The audience listens from a specially-constructed concrete bunker some thirty miles from the stage, and the band plays its instruments by remote control from a spacecraft in orbit around the planet (or around a different planet).

Notes

  1. 136 dB is approximately the threshold of pain, [41] and is about as loud as either the sound made by a jet airplane taking off 100 metres (330 ft) away [42] or by the loudest human voice shouting 1 inch (2.5 centimetres) away from the ear. [43]

The decibel is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 101/10 or root-power ratio of 101/20.

<span class="mw-page-title-main">Weighting filter</span>

A weighting filter is used to emphasize or suppress some aspects of a phenomenon compared to others, for measurement or other purposes.

Dynamic range is the ratio between the largest and smallest measurable values of a specific quantity. It is often used in the context of signals, like sound and light. It is measured either as a ratio or as a base-10 (decibel) or base-2 logarithmic value of the ratio between the largest and smallest signal values.

<span class="mw-page-title-main">Manowar</span> American heavy metal band from New York

Manowar is an American heavy metal band from Auburn, New York. Formed in 1980, the group is known for lyrics based on fantasy and mythology, as well as numerous songs celebrating the genre and its core audience. The band is also known for a loud and emphatic sound. In an interview for MTV in February 2007, bassist Joey DeMaio lamented that "these days, there's a real lack of big, epic metal that is drenched with crushing guitars and choirs and orchestras... so it's nice to be one of the few bands that's actually doing that". In 1984, the band was included in the Guinness Book of World Records for delivering the loudest performance, a record which they have since broken on two occasions. They also hold the world record for the longest heavy metal concert after playing for five hours and 1 minute in Bulgaria in 2008. They also have been known for their slogan "Death to false metal".

<span class="mw-page-title-main">Blue Cheer</span> American rock band

Blue Cheer was an American rock band that initially performed and recorded in the late 1960s and early 1970s and was sporadically active until 2009. Based in San Francisco, Blue Cheer played in a psychedelic blues rock or acid rock style. They are also credited as being some of the earliest pioneers of heavy metal, with their cover of "Summertime Blues" sometimes cited as the first in the genre. They have also been noted as influential in the development of genres as disparate as punk rock, stoner rock, doom metal, experimental rock, and grunge.

<span class="mw-page-title-main">Headphones</span> Device put on or in the ears that plays sound

Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earphones or, colloquially, cans. Circumaural and supra-aural headphones use a band over the top of the head to hold the drivers in place. Another type, known as earbuds or earpieces, consists of individual units that plug into the user's ear canal; within that category have been developed cordless air buds using wireless technology. A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication, a headset is a combination of a headphone and microphone.

Aircraft noise pollution refers to noise produced by aircraft in flight that has been associated with several negative stress-mediated health effects, from sleep disorders to cardiovascular disorders. Governments have enacted extensive controls that apply to aircraft designers, manufacturers, and operators, resulting in improved procedures and cuts in pollution.

<span class="mw-page-title-main">Dynamic range compression</span> Audio signal processing operation

Dynamic range compression (DRC) or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range. Compression is commonly used in sound recording and reproduction, broadcasting, live sound reinforcement and some instrument amplifiers.

<span class="mw-page-title-main">Audio system measurements</span> Means of quantifying system performance

Audio system measurements are used to quantify audio system performance. These measurements are made for several purposes. Designers take measurements to specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative defects of an audio path are within limits considered acceptable. Audio system measurements often accommodate psychoacoustic principles to measure the system in a way that relates to human hearing.

Sound pressure or acoustic pressure is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit of sound pressure is the pascal (Pa).

dB drag racing is a competition rewarding the person who can produce the loudest sound inside a vehicle. The "dB" means decibels of sound pressure level (SPL). In these competitions, SPL of over 140 decibels is common; and the international record in 2003 was 171.5 dB, with records as high as 180 dB claimed more recently.

Noise control or noise mitigation is a set of strategies to reduce noise pollution or to reduce the impact of that noise, whether outdoors or indoors.

<span class="mw-page-title-main">Sound level meter</span> Device for acoustic measurements

A sound level meter is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. The diaphragm of the microphone responds to changes in air pressure caused by sound waves. That is why the instrument is sometimes referred to as a sound pressure level meter (SPL). This movement of the diaphragm, i.e. the sound pressure, is converted into an electrical signal. While describing sound in terms of sound pressure, a logarithmic conversion is usually applied and the sound pressure level is stated instead, in decibels (dB), with 0 dB SPL equal to 20 micropascals.

<span class="mw-page-title-main">Noise-induced hearing loss</span> Medical condition

Noise-induced hearing loss (NIHL) is a hearing impairment resulting from exposure to loud sound. People may have a loss of perception of a narrow range of frequencies or impaired perception of sound including sensitivity to sound or ringing in the ears. When exposure to hazards such as noise occur at work and is associated with hearing loss, it is referred to as occupational hearing loss.

Don't Lose the Music is a national campaign launched by the RNID, the charity representing the 9 million deaf and hard of hearing people in the UK.

<span class="mw-page-title-main">Hearing conservation program</span>

Hearing conservation programs are programs that should reduce the risk of hearing loss due to hazardous noise exposure, if implemented correctly and with high quality. Hearing conservation programs require knowledge about risk factors such as noise and ototoxicity, hearing, hearing loss, protective measures to prevent hearing loss at home, in school, at work, in the military and, and at social/recreational events, and legislative requirements. Regarding occupational exposures to noise, a hearing conservation program is required by the Occupational Safety and Health Administration (OSHA) "whenever employee noise exposures equal or exceed an 8-hour time-weighted average sound level (TWA) of 85 decibels (dB) measured on the A scale or, equivalently, a dose of fifty percent." This 8-hour time-weighted average is known as an exposure action value. While the Mine Safety and Health Administration (MSHA) also requires a hearing conservation program, MSHA does not require a written hearing conservation program. MSHA's hearing conservation program requirement can be found in 30 CFR § 62.150, and is very similar to the OSHA hearing conservation program requirements. Therefore, only the OSHA standard 29 CFR 1910.95 will be discussed in detail.

Micronecta scholtzi, the lesser water boatman, is a species of pygmy water boatman in the family Micronectidae. It was first described by Franz Xaver Fieber in 1860. They are some 2 mm long and are common in freshwater ponds and lakes across Europe, preferring stagnant to moderately moving water. In Central Europe, the genus Micronecta is represented by five species, as follows:

<span class="mw-page-title-main">Noise in music</span> Unpitched, indeterminate, uncontrolled, loud, unmusical, or unwanted sound

In music, "noise" has been variously described as unpitched, indeterminate, uncontrolled, convoluted, unmelodic, loud, otherwise unmusical, or unwanted sound, or simply as sound in general. The exact definition is often a matter of both cultural norms and personal tastes. Noise is an important component of the sound of the human voice and all musical instruments, particularly in unpitched percussion instruments and electric guitars. Electronic instruments create various colours of noise. Traditional uses of noise are unrestricted, using all the frequencies associated with pitch and timbre, such as the white noise component of a drum roll on a snare drum, or the transients present in the prefix of the sounds of some organ pipes.
