A literature review on noise cancellation techniques in audiometry testing
Author(s): Velmurugan S
Abstract: This paper identifies current research on noise canceling methods applied to hearing screening tests. Investigations are also being conducted on audiometry issues and solutions related to real-time noise reduction techniques. Background noise levels at testing locations are reduced down below the threshold specified by the American National Standards Institute (ANSI) using sound proof studios. The test must be performed in an environment where ambient noise levels are less than the maximum permitted noise levels to avoid false positive screening findings. Excessive ambient noise is a major problem for hearing screening since it masks pure tone stimuli, particularly at frequencies below 500 Hz. As a result, false findings are produced. Ambient noise might make it difficult for those with hearing loss to understand what is being said. In audio-metric testing, noise reduction strategies have been addressed in a variety of ways over the years. This is a survey of journals in the field of noise canceling techniques in hearing screening, with the most recent articles highlighted.
