A sound level meter is a device for measuring the sound pressure level that is commonly used in noise pollution studies to quantify all kinds of noise, but especially industrial and environmental noise, especially aircraft noise. However, the figure displayed by a meter in dB Sound Pressure Level (SPL) does not necessarily correspond to the sound perception of man; For this weighting is necessary. The current international standard defining the recommendations for sound level meters is IEC 61672: 2003 which requires the incorporation of a frequency-weighting filter and also describes other frequency weightings C and Z weighting (zero). The old B and D frequency weightings are now obsolete and are no longer described in the standard. The classic sound level meter is used for spot measurements as opposed to the noise dosimeter or exposure meter which is worn by an employee for an extended period, representative of the usual sound exposure to assess the level of daily exposure (Lexd).
