Description

<p>　　For the hearing impaired, masks and shields to protect against the spread of the new coronavirus infection COVID-19 cause additional hearing difficulties. We attempted to quantify this additional listening burden using an application to evaluate the listening environment. An application was created that combines speech recognition AI with the CI2004, a Japanese hearing test battery for cochlear implant recipients.</p><p>　　The accurate response rate was 95% when the examination was administered in the quiet. With poorer sound sources or noise, however, the percentage of accurate answers decreased. Although the proportion of correct answers did not significantly drop decrease significantly when the test was administered in a noisy environment with just a mask, it fell significantly when the mask was combined with shielding.</p><p>　　 Our findings suggest that many hearing-impaired individuals find it challenging to understand what is being said by a person hiding talking from behind a shield in noisy settings. Masks do not adversely affect hearing as much as shields, and should be used with consideration for the hearing impaired who use lipreading. It is easy to assess hearing problems in various environments using the same test parameters.</p>
