Low noise concrete vibration screen with large power

Structural Vibration as a Noise Source on Vibrating Screens

The noise radiated by the screen at frequencies below 1 kHz was examined because this frequency range accounts for about 80% of the overall A-weighted sound power level. The dominant noise sources at these frequencies must be addressed to reduce the radiated noise. Since the screen is relatively large,

Noise control

Noise is measured by sound pressure level which is expressed as a power ratio and calibrated in decibels (dB). The ear has a large dynamic range in audio perception with the ratio of the quietest to the most immediately dangerous sound level (capable of causing permanent damage to the ear) being in the order of 1:1 trillion.

Concrete VIbrating Tips

Formwork vibration: Formwork vibration is commonly used in precast concrete construction and involves mounting the vibrators to the outsides of the concrete forms.For larger pours, the external form vibrators are often spaced 6 feet apart. Surface vibration: With surface vibration, large vibrators (sometimes called "jumpers") are directed manually onto the surface of the poured concrete.

Noise - Basic Information : OSH Answers

The noise of boilers in a power house is relatively constant and can therefore be classified as continuous. Most manufacturing noise is variable or intermittent. Different operations or different noise sources cause the sound changes over time. Noise is intermittent if there is a mix of relatively quiet and noisy periods.
