Can the hotel hear others? Can others hear me?
Since you can hear others' voices, others can certainly hear yours. The way of sound transmission between you is the same. The problem is that the hotel has no sound insulation. In order to save money in architectural design, some hotels have no sound insulation because the wall materials are ordinary. In order to increase the use of space, the walls are all partitions, and the sound insulation effect is poor. There are also space design problems, which will also affect the sound effect.
Sound is a sound wave generated by the vibration of an object, and it is a wave phenomenon that is transmitted through a medium (air or solid or liquid) and can be perceived by human or animal hearing organs. The source of the object sound that vibrates (vibrates) at first. Sound is a kind of wave, and the frequency of sound that human ears can recognize is between 20 Hz and 20 Hz-20Hz-20000Hz. In physics, sound is produced by the vibration of an object, and the object that emits sound is called a sound source. The number of times an object vibrates in one second is called frequency. The unit is hertz, and the letters are hertz. The human ear can hear the sound of 20~20000Hz, and the most sensitive is the sound of 200~800Hz.
