acoustic noise reducers

A reactive muffler is an acoustic noise reduction device without sound-absorbing materials. It creates changes in acoustic impedance through sudden changes in pipe cross-sections (expansion chambers) or side-connected resonance chambers, causing sound waves to reflect and cancel each other out via interference, so as to reduce noise at specific frequencies.

Product features:

  •  Easy installation, good noise reduction effect, long service life and other characteristics.

  •  Customized design can be carried out according to the user's needs. (Product materials, installation methods, product colors, etc.

  • The muffler is made of high-quality steel and has undergone galvanization treatment, featuring excellent heat resistance and corrosion resistance, which greatly extends the service life of the product.


The mufflers we produce, whether they are resistive mufflers, reactive mufflers, composite mufflers or gas venting mufflers. All materials are uniformly made of high-quality steel plates, high-quality perforated plates , and high-quality sound-absorbing cotton. The noise reduction of all mufflers ranges from twenty to fourty-five decibels, and there will be certain differences in noise reduction among different muffler specifications. Therefore, we recommend that the purchaser provide the corresponding on-site data so that we can carry out the design, thereby enabling the muffler to achieve the best noise reduction effect.

Metal Acoustic Barrier
Metal Acoustic Barrier
metal acoustic barrier is a noise reduction measure with metal plates as the main body and sound-absorbing and sound-insulating materials installed inside. By physically blocking and converting sound energy, a sound shadow zone is established between the noise source and the sound reception point, achieving a noise reduction effect that attenuates the direct sound by 10~20 decibels.
