Speech perception of hearing impaired people using a hearing aid with noise supression algorithms

摘要

Often, individuals with hearing loss have difficulties understanding speech in noisy environments. AIM: It was the aim of this study to assess the performance of adult individuals with sensorineural hearing loss, associated with speech perception using digital hearing aids with a sound reduction algorithm called Speech Sensitive Processing, on and off, in the presence of noise. MATERIALS AND METHODS: This case study was performed with 32 individuals with sensorineural hearing loss of mild, moderate or mild to moderate level. Our evaluation involved a speech perception test, where we investigated the recognition of sentences in noise, in order to get a signaloise ratio, with a digital hearing aid. Result DESCRIPTION: The algorithm provided a benefit for most hearing impaired individuals, in the investigation of signaloise ratio and the results pointed to a statistically significant difference when the algorithm was on, compared to when the algorithm was off. CONCLUSION: The use of a sound reduction algorithm must be considered as a clinical alternative - since we observed an efficacy in noise reduction and heightened speech perception.
