AQH Share

AQH Share is a statistic that measures broadcast radio listenership.


AQH is an abbreviation for Average Quarter-Hour Persons (AQH Persons), defined by Arbitron (now referred to as Nielsen Audio) as the average number of persons listening to a particular station for at least five minutes during a 15-minute period.

Share is the percentage of those listening to radio in an Arbitron “market” (typically a metropolitan area) who are listening to a particular radio station.

Thus, AQH Share for a given station is mathematically expressed as [AQH Persons listening to station / AQH Persons listening to all market radio stations] * 100.


AQH Share is most often used in conjunction with TSL (Time Spent Listening) to measure listenership in a market. While AQH measures the average number of listeners to the station, TSL tracks the length of time listeners are tuned continuously to the station.
