Without a decibel meter, noise would become a controversial issue because people perceive noise differently. 10 different people will have 10 different opinions about what noise levels are within the normal range and when is it too loud or even perceived as disturbing noise. Sound level meters measure decibels accurately and thus help assessing noise nuisance and solving disputes. When such a decibel meter is used, the measured data can be classified into A and C ratings.
“without a decibel meter, noise would become a controversial issue because people perceive noise differently”
The PCE-MSM 4 decibel meter from PCE Instruments is ideally suited for measuring annoying and unhealthy noises in various environments, for instance at the workplace, during machine inspections, at construction sites or events. The way noises or sounds are perceived by the human ear depends on the frequency. In the environmental field, the A-weighting is the most common frequency weighting. When this weighting is used, the readings between 30 and 130 dB are displayed as dB(A). On the 4-digit LCD, the values are clearly displayed with large digits. The pitch of a sound depends on the frequency of pressure fluctuations. The number of oscillations of a sound wave per second is called the frequency and is expressed in Hertz (Hz). The higher the frequency, the higher the perceived sound.
Decibel measurements are becoming more and more important. Especially mobile measurements of traffic noise, workplace noise or noise nuisance in apartment buildings is becoming more and more popular. Recorded measurements over a longer period can be submitted to the relevant authorities as required.
