Speech in Noise (3 of 5)

Here we display the speech banana that shows some English speech sounds at their typical loudness and frequencies on an audiogram, or hearing test result. Note that speech sounds differ in their typical loudness and important frequencies for identification. You can use this figure to understand which speech sounds would be difficult based on your hearing test result. If the speech sound is above your hearing test result at a given frequency you may not be hearing those speech sounds.
When listening in noise, the loudness and frequency of the noise will also determine the speech sounds that will be most disrupted. Speech sound such as "f", "th", and "s" tend to be quiet and are commonly difficult understand in high-frequency noise.
