Background:Hearing loss not only causes a deficiency in a person’s capacity to perceive sounds, but it also brings about psychosocial compromises. The present study was conducted to compare efficacy of two different hearing aids in patients with hearing loss. Materials & Methods: 72 patients with hearing loss were divided into 2 groups. Each group had 36 patients. Group I comprised of channels ranged from 1 to 16. Group II had the number of channels ranged from 2 to 16. The minimum frequency ranged from 100 to 160 Hz and the maximum from 5,800 to 7,600 Hz. Total individual subjective satisfaction (TISS) scores were also recorded. Results: The group I had 17 males and 109 females and group II had 20 males and 16 females. The mean TISS score at 1 month, 6 months and 12 months in group I was 50, 55 and 63 and in group II was 60, 68 and 75 respectively (P< 0.05). The difference was significant (P< 0.05). Conclusion: Devices with good technologic features such as more channels, a lower minimum frequency, and a higher maximum frequency result in better hearing.
