The reason why our voice is so strange and unfamiliar in a recording lies in a well-known physical phenomenon.
The sound waves that we emit when we speak travel through the air to the microphone. In this medium, part of the low-frequency sounds , generally those below 300 hertz, dissipate and do not reach the recording equipment , causing the loss of nuance . To this must be added the fact that we are used to hearing ourselves in a special way. When speaking, sounds are transmitted through the bones of the head, which act as a sounding board. Hence, we perceive our words in lower tones than the interlocutor.
