| Abstract | ||
| :Communication difficulties are a negative result of sensorineural hearing loss (SNHL) particularly in noisy and/or reverberant environments. Hearing aids can be efficent in compensating hearing loss as regard loudness of sound but may be not sufficient enough for other difficulties such as temporal and frequency resolution particularly in challenging listening conditions such as in background noise, large spaces like theatres and places with high degree of reverberation. Assistive listening devices improve the signal-to-noise ratio (SNR) in different ways: by reducing background noise, minimizing effects of distant sound source, and compensating for poor acoustics as reverberations. ALD refers to any device assist individual hearing aids or cochlear implants to help individuals to detect surrounding sounds. ALDs are used to increase individuals' hearing ability in various conditions, as in the classes, theatres, religious institutions, and airports. They enable greater independence, reduce the stress of daily activities, and improve the quality of life for people with impaired hearing. | ||
