Domestic sound receiver for partition walls

Perhaps you might be interested to know:

Does the wall-separated listening device have any background noise?

There is no noise. Sound amplification through the wall is not like radio frequency reception, which is subject to electromagnetic interference, so there is no noise. Some customers have reported noise, but it is just because the sound acquisition head is too sensitive. When using the sound amplification device on the wall, avoid sliding to avoid this phenomenon.

Is the effect good?

I can better explain this question to you by saying: We listen.10The effect of listening through a wall depends on the volume of the speaker's voice, so it cannot be directly said to be good or bad. The effect of listening through a wall is determined by“wall”The quality and volume of the sound determine the effect. Therefore, as long as the conditions are met, the effect is very good, and the opposite is not good! The sound in a normal-sized room is quite good. If you listen through the door, the effect is best!!

What's the difference between professional soundproof partitions and ordinary ones?

Professional sound-inspection walls have more functions, including frequency band adjustment for different wall properties, so it is suitable for“wall”的要求更低，应用场合更广，所以叫“Professional”The application of this model is relatively limited, that's all. If your purpose is personal entertainment, we recommend this model. If the commercial aspect is stronger, we recommend the professional wall listening.
