Hearing Loss Simulator
In this simulation* you can discover how sensorineural hearing losses affect hearing. This type of hearing loss is by far the most frequent and is caused by a dysfunction of the inner ear, many times due to excessive exposure to noise.
- Mild Hearing loss: People with mild hearing loss are unable to hear soft sounds and have difficulty understanding speech clearly in noisy environments.
- Moderate hearing loss: This simulation reflects a typical high frequency moderate hearing loss. People with this type of hearing loss are unable to hear soft and moderately loud sounds and have considerable difficulty understanding speech particularly in background noise.
* The hearing loss simulation is based on two algorithms which simulate recruitment  and spectral smearing .
