This portable high-accuracy sound level meter has a large easy-to-read illuminated LCD screen that displays the sound pressure level (SPL) numerically and graphically in real time. The sound level meter calculates the equivalent continuous sound level Leq (LXeq). Measuring range: 25 … 136 db (A)
1 Οκτ 2018 · A Class 1 sound level meter is generally seen as more accurate than a Class 2 meter; and, A Class 1 sound level meter is able to measure sound over a wider frequency range than a Class 2 meter.
6 Οκτ 2020 · If you already have a sound level meter or have been looking for one, you have likely come across the terms Class 1 or Class 2. In this article, we will explain the difference between the two meters and give some excellent examples of both types of meter.
Type 1 or Class 1 sound meters are used for incredibly precise noise measurements (such as in laboratories) as they are able to measure the smallest sound levels. Class 2 sound level meters are usually used in workplaces for assessing and measuring noise.
A decibel meter is a sound pressure measuring instrument for standardized measurements that uses the decibel scale. For this reason, the decibel meter is also known as a sound pressure level (SPL) meter. Other common names include noise meter and sound level meter. A decibel meter uses a microphone to capture sound.
11 Οκτ 2011 · In the current standard, IEC 61672-1:2002, there are two levels of tolerance and these are known as Class 1 and Class 2. In an ideal situation, the instrument would meet the centre point or design goal of these criteria exactly and every sound level meter would measure exactly the same.
A sound level meter or noise dosimeter should meet the relevant standards such as IEC61652 and the older ones IEC60651 and IEC60804.
