The speech banana is a region on an audiogram that represents the frequencies where most speech sounds occur, typically ranging from 125 Hz to 8000 Hz. Providers can use the speech banana to better understand which speech sounds and other common sounds an individual can access based on their hearing ability. By comparing the individual's audiogram to the speech banana, providers can identify which sounds fall within their hearing range.
