  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Record breaking formula one fan noise control

    Problem: an extract system fan drone creating a potential environmental noise problem. Solution: aerodynamic engineering instead of silencers – in keeping with the Red Bull Technology ethos. The conventional technique used to reduce fan tones like this is a silencer – a large, palliative silencer that doesn’t tackle the source of the ...
