Sound Meaurement

Product Details:

The determination and control of Air bone noise has been a vital problem in recent years. It is now generally appreciated that high level noise is detrimental to the normal health and efficiency of the individual, and frequently indicates a fault in the manufacture or design of a product.

Sound waves cause variations in the normal atmospheric pressure. This variation in pressure is measured in dynes per square centimeter. For convenience, a logarithmic scale of decibels is used for sound level measurements. The sound pressure level is defined as the ratio in decibels of the magnitude of the sound pressure to the standard reference sound pressure of 0.0002 dyne per square centimeter.

The Sound Level Meter provides the essential basic instrument for such investigations, since it measures, on an internationally standardized decibel scale, the value of the alternating pressure waves of the air which are caused by the sound.

ACD is making available instrument S-3000 which confirms to the requirements of ‘Type 2’ instrument as per IS 9779-1981.

This instrument consists of electret microphone, impedance matching circuits, high gain amplifier, attenuator, precise weighting networks and digital meter.

The instrument with accessories is housed in a sturdy portable case.

Features:

• Electret Condenser Microphone
• Direct Digital Reading
• 35 db to 130 db Range
• A & C Weightage
