What is a SPL meter used for?
Sound Level Meter Functions A sound level meter can be used for measuring sound or noise* for Community Noise Analysis, Building Acoustics, Industrial Noise Control, Machinery Noise Analysis, and further applications.
How do you measure SPL?
The unit measure of SPL is decibels (dB). It is measured with a Sound Pressure Level Meter, such as the Pulsar Nova. Sound enters the meter through a microphone, and then the meter evaluates the sound values by converting them into electrical information and the measurement values in decibels are displayed.
What is an SPL test?
The SPL meter is an instrument that determines the sound level by measuring the sound level pressure. Sound enters the SPL meter by means of a microphone input. The sound is then evaluated within the SPL meter and measurement values in decibels are displayed.

How do you calculate SPL distance?
In a free field – a doubling of the distance from a noise source reduces the sound pressure level with 6 decibel. A “free field” is defined as a flat surface without obstructions….Example – Rifle Shot and Sound Pressure at Distance.
| Distance (feet) | Sound Pressure Lp (decibel) |
|---|---|
| 1.25 | 134 |
| 2.5 | 128 |
| 5 | 122 |
| 10 | 116 |
How do I calibrate my SPL meter?
SPL Calibration Procedure
- Select the Mic/Meter tab of the Preferences panel.
- If making measurements with a microphone select the Mic or Z Weighted SPL Meter option.
- Open the REW SPL meter by clicking the SPL Meter button in the toolbar then press the Calibrate button.

What is sound pressure level and how is It measured?
Sound pressure level (SPL) or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level (20 µPa, which is usually considered the threshold of human hearing at 1 kHz).
What instrument measures noise level?
Also known as a noise dosimeter, decibel reader, or noise level meter, a decibel meter is a device that measures the intensity of sounds using the decibel (dB) unit. It lets you know just how soft or how loud noise is. A normal conversation, for example, would measure about 50 decibels.
What is sound level unit?
The SI unit for sound pressure p is the pascal. Sound pressure level or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels above a standard reference level.
