Brachot Through a Microphone
Does one fulfill one's obligation of a bracha if one hears a bracha through a microphone? One of the primary sources on this topic is the mishna (Rosh Hashana 27b) which states that if someone blows the shofar into a pit, if one hears an echo of the blow, one doesn't fulfill one's obligation. The gemara (28b) establishes that this only applies to those who are standing on the lip of the pit, but those inside of the pit certainly fulfill their obligation since they hear the blow directly. Shulchan Aruch 587:1 codifies this as halacha. [1] Based on this, one could have begun to discuss whether hearing a voice over a microphone is considered like an echo or the original sound itself. The distinction between an echo and a microphone is clear; an echo causes a mixture of sounds, whereas the microphone simply amplifies the original sound.[2]
The main discussion of the poskim, however, centers around whether the sound that is produced by the microphone is considered the original sound that went into it. Rav Moshe Feinstein[3] writes that it seems that one could fulfill any mitzvah, which one fulfills through speech, by hearing it amplified by a microphone. He notes, though, that this leniency would not apply to Kriyat Shema or Birkat HaMazon. He reasons that since the voice is heard as a direct and immediate result of the speaker it is considered like regular speech and not an echo. Even though the microphone converts the sound waves into an electrical signal which is then used to produce amplified sound waves, the resulting sound waves should be considered no different than regular sound waves that are creates as a person speaks. He concludes with hesitation being that microphones are a new invention and shouldn't be introduced into Jewish practices.
Interestingly, Rav Shlomo Zalman Auerbach records a conversation he had with the Chazon Ish, in which the Chazon Ish espoused an opinion very similar to Rav Moshe. On the other hand, Rav Shlomo Zalman Auerbach felt that since the microphone converts the sound waves into an electrical signal and produces a new sound, one certainly can not fulfill mitzvot through a microphone since the sound one hears isn't the same one that was original one.[4] A number of poskim agreed with Rav Shlomo Zalman's logic.[5]
