We generate many sounds in our daily lives when we use television, audio equipment, and home appliances such as air conditioners, vacuum cleaners, and washing machines. There are also sounds caused by human activities such as walking and opening and closing doors. Among these sounds, undesirable sounds are referred to as neighborhood noise or daily life noise. When it comes to neighborhood noise and daily life noise, a certain amount of noise must be tolerated as daily life noise because you are living in shared housing. However, even sounds that aren’t bothersome during the day can be louder than expected at night and cause issues, so please be careful. Also, be sure to conduct soundproofing measures on a regular basis.
