# Someone who's hard of hearing may use a hearing aid which was turned on before [[Shabbat]].

Rav Shlomo Zalman in his teshuva Minchat Shlomo 1:9 is dealing with microphones and concludes that a change in a voltage of a current isn't molid but still using a microphone is forbidden since it is audible and is a violation of Avsha Milta, degrading Shabbat. However, regarding hearing aids the Shaarim Metzuyim Bhalacha cites a letter from Rav Shlomo Zalman Auerbach that it is permitted to turn up a hearing aid on Shabbat and as there's no issue of muktzeh with a hearing aid that is already on. </ref> | ||
# It is permitted to use a hearing aid on Shabbat even if it automatically adjusts the volume depending on the loudness of the environment.<ref>Rav Asher Weiss in Minchat Asher 1:31:1 writes that using hearing aids which automatically adjust depending on your surrounding. In a quiet place it amplifies noise and in a loud place it lowers the amplification. He explains that it is permitted to use them and move around while wearing them since either that isn't considered your action that the device changed its functionality or that it is but it is permitted since the accomplishments of the change in voltage in the circuit are insignificant and don't violate makeh bpatish, boneh, or molid. The automatic mode of hearing aids is described here: https://www.boystownhospital.org/knowledgeCenter/articles/hearing/Pages/PutYourHearingAidsOnAutomatic.aspx.</ref> | # It is permitted to use a hearing aid on Shabbat even if it automatically adjusts the volume depending on the loudness of the environment.<ref>Rav Asher Weiss in Minchat Asher 1:31:1 writes that using hearing aids which automatically adjust depending on your surrounding.
