  • Bespoke noise protection: AERZEN relies on the advantages of reactive silencers

    With reactive silencers, AERZEN reduces the noise emissions on the discharge side of its screw compressors, positive displacement blowers, and rotary lobe compressors. The innovative concept of these reactive silencers is superior to classic dissipative silencers in many respects. The sound waves developing on the discharge side of a Delta Screw compressor made by AERZEN can reach 170 to 190 dB. ...

  • New techniques to determine specific noise for increasing the effectiveness of continuous unattended noise monitoring systems

    Continuous, unattended noise monitoring systems can immediately alert you should noise levels exceed defined criteria. Once alerted to an exceedance, operators can act to return levels to compliance. This approach has two significant limitations. Firstly the operator can only take action after the breach has occurred and therefore systems are only able to inform owners about problems that have ...

  • Occupational noise - Noise control at the workplace starts with measurements

    We often automatically turn to personal protective equipment in order to restrict noise. Yet there are other solutions. NoiseAtWork software enables us to map the situation quickly. It has been scientifically proven that exposure to noise which exceeds 80 dB(A) causes hearing loss, but lower levels can also cause physical and mental complaints. Noise also has a disruptive effect on communication ...
