In modern urban life, sound insulation effect has become one of the important criteria for measuring the quality of room environment. A good sound insulation effect means a quieter, more private and more comfortable living environment. So, how to check the sound insulation effect of the room? Let’s explore it below.
1. Use sound testing equipment
The most direct and simple way is to use professional sound testing equipment. These test instruments can evaluate the sound insulation of a room by emitting sounds of a certain frequency and then measuring the corresponding reflections and echoes. This method requires professional testing to obtain more accurate results. But it also requires certain fees and time costs.
2. Manually test sound isolation
In addition to using test instruments, we can also evaluate the sound insulation effect of the room through manual testing. This method requires two people to test: one person makes the sound in the room, and the other person listens to the sound level in an adjacent room or corridor. By testing the difference in sound size at different frequencies, you can evaluate the sound insulation effect of a room.
3. Refer to building standards
Finally, you can refer to local building codes to find out how soundproofing your room should be. These standards usually include sound isolation requirements at specific frequencies. If your room meets the standards, it is considered to have good sound isolation.
4. Mobile app
You can also go online to find some apps that specialize in testing noise, and test the noise level through your mobile phone. Although it is not 100% accurate, it will not be too biased.

In short, sound insulation effect is one of the important factors affecting the living environment. Through the above methods, you can understand whether the sound insulation effect of your room meets your expectations, so you can take appropriate measures to improve it.
