3. RS PRO LCD sound level meter
A sound level meter is used for acoustic measurements. It is usually a portable instrument with a microphone. The microphone's diaphragm responds to changes in air pressure caused by sound waves. Therefore, the device is sometimes referred to as a sound pressure level meter.

4. Voltcraft Schallpegel-Messgerät SL-10 R
The housing of the Voltcraft SL-10 R sound level meter is made from 85% recycled granulate. Additionally, conventional epoxy composite material is avoided for the carrier material of the internal circuit board, opting instead for ceramic as the substrate. Technically, the SL-10 R corresponds to the previous SL-10 and allows for quick and easy sound level measurements with linear frequency weighting (dBA) using the preset parameters. It is ideal for simple measurement of environmental noise or other sound sources. Furthermore, the device features two different measurement intervals (Fast/Slow) for various applications. The color of the housing may slightly vary due to the recycled granulate.

5. PCE Instruments Data logger
Class II sound level meter with data logger, USB interface, measurement range of 30 - 130 dB, LC display, including software, storage for up to 32,700 measurement values. The sound data logger PCE-322A is particularly suitable for measuring noise pollution in the fields of industrial, health, safety, and environmental monitoring. The data logger has a logging function that allows for the storage of up to 32,700 measurement values, making it ideal for long-term monitoring. The PCE-322A data logger can be connected to a PC via a USB cable. Live measurement is also possible with the sound level meter, and the data can be viewed and analyzed directly. The software provides data representations in graphic formats and tables. This data can be transferred to Microsoft Excel, for example. The sound level meter features an analog output and offers additional features that are unique in its class.
