Time spent listening (TSL) is one of the measurements surveyed by Nielsen Audio in determining ratings for radio stations in the United States. It is the equivalent of Average Time Exposed (ATE), Daily or Weekly.
TSL is defined as the amount of time the average listener surveyed spent listening to each radio station at one time, before changing the station or turning it off. Alternately, it is an estimate of how long the average panelist (listener) was exposed to a particular station or stations for a specific time period.
TSL trends are used in conjunction with AQH share ("AQH") to evaluate listenership to a station. In some radio formats, a station with low AQH (number of listeners) but high TSL is considered more attractive to advertisers than a high AQH / low TSL station, because the station's listeners are more likely to stick with the station through commercial breaks and hear the paid advertisements.

An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness contours. By definition, two sine waves of differing frequencies are said to have equal-loudness level measured in phons if they are perceived as equally loud by the average young person without significant hearing impairment.
DXing is the hobby of receiving and identifying distant radio or television signals, or making two-way radio contact with distant stations in amateur radio, citizens' band radio or other two-way radio communications.

Audience measurement measures how many people are in an audience, usually in relation to radio listenership and television viewership, but also in relation to newspaper and magazine readership and, increasingly, web traffic on websites. Sometimes, the term is used as pertaining to practices which help broadcasters and advertisers determine who is listening rather than just how many people are listening. In some parts of the world, the resulting relative numbers are referred to as audience share, while in other places the broader term market share is used. This broader meaning is also called audience research.

The most common advertisements are "spot commercials", which normally last for no more than one minute, and longer programs, commonly running up to one hour, known as "informercials".
