During the factory qualification testing process, the acoustic indicators of the tested products are either used as sound proof rooms or sound proof rooms. So how do you determine whether a room is fully soundproof or semi-soundproof?

The entire sound-proof room has six sides for sound absorption, and the top, four walls and ceiling panels are equipped with sound absorbing tips. In this way, all six sides absorb the sound emitted by the sound source without producing any reflexes. The semi-soundproof room has only five sides with sound-absorbing treatment, and the floor is not equipped with sound-absorbing tips. Generally, the floor is made of the original muddy ground of the room, and the upper surface is equipped with sound-absorbing carpet or paste-on carpet. Therefore, the ground of the semi-silencer room forms a reflective surface, which is the difference between full silencer and semi-silencer in terms of actual quality.

During the actual product testing process, some products require reflective surfaces and some do not. Those that require reflective surfaces will use a semi-silencer, and those that do not will use a full-silencer. Are you currently in a fully soundproof room or a semi-soundproof room?
