Speech Variable Processing - Frequency Contrast is Key to Speech Clarity
CLARITY REQUIRES FREQUENCY CONTRAST
If speed is the key to accuracy, frequency contrast is the key to clarity. Frequency contrast is the difference in the amplification across frequencies for an incoming sound. Correctly identifying these contrasts plays a large role in speech clarity. A healthy cochlea amplifies sound to maintain this natural level difference across frequencies. With a sensorineural hearing loss, the ability to amplify correctly at different frequencies is diminished, resulting in a loss of frequency contrast.
