A multichannel compression strategy for a digital hearing aid
Multi-channel compression schemes are a practical method of mapping the wide dynamic range of speech signals into the reduced dynamic range of hearing impaired listeners. These systems address two of the shortcomings of single-channel compression systems: (1) the reduction of gain as a result of narrow-band non-speech stimuli and (2) the reduction of gain that often occurs when high-frequency s...
متن کاملDigital Hearing Aid – a Review
In the rural sector of India there is a large number of hearing impaired persons. With moderate or acute hearing loss Hearing impaired persons, suffer from opportunities for communicating with others Presently the conventional analog hearing aids have a number of functional limitations such as fixed frequency, lack of flexibility, can’t distinguish speech from noise, etc. The Digital hearing ai...
متن کاملHearing aid fitting in a digital age
This paper introduces SoundPoint, a new patientassisted fine tuning process that complements the traditional fitting process by placing control of sound quality in the hands of the patient. The SoundPoint system offers an elegant alternative to the method of ‘interview and adjust’ by providing any patient with the ability to navigate through a perceptual world of possible hearing aid adjustment...
متن کاملPerceptual acclimatization post nonlinear frequency compression hearing aid fitting in older children.
PURPOSE In this study, the authors evaluated the effect of frequency compression hearing aids on speech perception ability and the time course and magnitude of acclimatization-related changes. METHOD Participants included children ages 11-18 years. Speech perception ability was evaluated over well-controlled baseline, treatment, and withdrawal study phases. Study-worn hearing aids were indivi...
متن کاملDevelopment of Digital Signal Processing Platform for Digital Hearing Aid
There has been a tremendous growth for the past few years in the field of VLSI and real time signal processing. Number of signal processing algorithms have been developed which allow the user to process real time signals such as speech to accomplish the signal with desired quality. Development of CMOS technology provides wide selection of low power FPGAs to be used in Digital system design. Thi...
