What is the reason for the loud singing in the bathroom?

1, because when the sound wave is sent out, it will be reflected when it touches an object, but the reflected sound wave will be weakened because of energy consumption and long distance. There are few things in the bathroom, which can reduce the chance of sound wave reflection. At the same time, the space is relatively small and the sound is relatively concentrated, which sounds good.

2. The environment of the bathroom is different from other rooms. Limited space and articles in the bathroom can make the sound reflection effect reach an excellent state. The walls of the bathroom are smooth and solid, the washbasin and bathtub are hard, and the big floor is not covered. These planes are ideal high-frequency reflecting surfaces. The sound that people make when they sing is a high-frequency sound. High-frequency sound is easy to attenuate when propagating because of its long wavelength, and low-frequency sound is easy to diffract and not easy to attenuate because of its short wavelength. In an ordinary room, high-frequency sound is easily absorbed by various items placed in the room and easily attenuated, while low-frequency sound will remain.
