Nura is a consumer electronics company based in Melbourne, Australia, that designs and manufactures headphones with personalized sound technology. Nura's proprietary technology automatically measures the user's hearing sensitivities to different frequencies by monitoring sounds generated from the inner ear. [1] This hearing measurement process takes 1–2 minutes. [2] The headphones then adapt their frequency response to the user's hearing, allowing them to hear more detail when listening to music. [3]
Nura's debut product, the Nura phone, launched on October 3, 2017. [4]
In July 2018, Nura became the first company to add active noise cancellation to a headphone via a software update. [5]
In April 2023, Nura was acquired by Denon, a part of the Masimo Corporation, to integrate their personalized audio technology into Denon earbuds and headphones. [6]
Nura was founded in 2015 by Dr. Luke Campbell, Dr. Dragan Petrović, and Kyle Slater. [7]
Nura was able to develop their debut product, the Nuraphone, with funding from the Melbourne Accelerator Program, HAX (a hardware accelerator program based out of Shenzhen, China), venture capital, and the use of a crowdfunding campaign on Kickstarter. In 2015, the Melbourne Accelerator Program granted Nura an Entrepreneurial Fellowship, which provided monetary funding as well as office space and mentoring. In 2016, Nura joined HAX, and in the same year, they ran a crowdfunding campaign on Kickstarter to raise funds to begin mass production of the Nuraphone. [8] The Kickstarter campaign ultimately raised $1.8 million (USD) from 7,730 backers to become the largest Kickstarter campaign in Australian history. [9] In May 2017, Nura raised a $6 million (AUD) seed-funding round, which was led by Blackbird Ventures, [10] with additional investment from SOSV, [11] Qualgro, [12] Sean Parker, [13] Craig Barratt, [14] the San Francisco 49ers and partners of Perkins Coie. The seed-funding round was followed by a $21 million (AUD) series A round also led by Blackbird Ventures.
Nura officially began operations on October 3, 2017, giving the general public access to the Nuraphone. [15]
The Nuraphone is a headphone that personalizes sound by measuring how the human ear responds to different sound frequencies [16] [17] and is patent-protected as the only consumer electronics headphone to do so. [18]
Nura released a free firmware update for the Nuraphone in July 2018 that enabled additional features such as active noise cancellation, audio pass-through, and enhancements to voice calls and button presses. [19]
In 2020, Nura released the NuraLoop wireless earbuds which repackaged the Nuraphone experience into a portable design intended to bring optimal sound performance to performers. The NuraLoop can be used both wired and wirelessly (16-hour battery life) allowing greater flexibility on the go. The NuraLoop was named an Innovation Award Honoree at CES in 2019.
In 2021, Nura launched their latest product, NuraTrue, which are wireless headphones with the company's signature personalized sound technology. NuraTrue was listed in TIME's 100 Best Inventions of 2021 and awarded "Best Earbuds for Personalized Sound" in Rolling Stone Audio Awards 2022.
Alongside NuraTrue, Nura launched NuraBuds exclusively on their subscription platform NuraNow in 2021. Unlike NuraTrue, NuraBuds cannot perform a hearing calibration, however a hearing profile created with any other Nura product can be imported onto the device.
The Nuraphone's personalization works by monitoring the user's otoacoustic emissions and then adjusting sound based on the measurements, [20] allowing the user to hear more detail when listening to music. [21] The Nuraphone has a patented design (Inova) that includes both in-ear monitors and over-ear cups, [22] and also features Tesla valves that circulate air through the ear cups to keep the user's ears cool during use. [23]
Nura won the Best of Innovation at the CES Innovation Awards 2018 for the Nuraphone. [24] The product also won the Red Dot Award 2018 Best of the Best in the consumer electronics category, the 2018 Good Design Australia Award for best product design in consumer electronics, [25] and the Gold at IDSA IDEA 2018 awards in the consumer technology category. [26] In 2021, the NuraTrue was listed in TIME's 100 Best Inventions of 2021 in the Custom Listening category, and in 2022, it was awarded Best Earbuds for Personalized Sound in Rolling Stone's Audio Awards.
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 speakers in place. Another type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal. 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 headphone and microphone.
Noise-cancelling headphones suppress unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing.
An otoacoustic emission (OAE) is a sound that is generated from within the inner ear. Having been predicted by Austrian astrophysicist Thomas Gold in 1948, its existence was first demonstrated experimentally by British physicist David Kemp in 1978, and otoacoustic emissions have since been shown to arise through a number of different cellular and mechanical causes within the inner ear. Studies have shown that OAEs disappear after the inner ear has been damaged, so OAEs are often used in the laboratory and the clinic as a measure of inner ear health.
