Do you ever wonder how loud your environment is? Or if it’s too loud for certain activities? There are devices called sound meters that can answer these questions for you! In this blog post, we will discuss everything you need to know about sound meters. We will cover what they are, how they work, and some of the different types available on the market. We will also provide some tips on choosing the right sound meter for your needs.

What is a sound metre?

A sound meter is a device that measures sound pressure level (SPL). This is also sometimes referred to as loudness. Sound meters are used in a variety of applications, such as industrial noise monitoring, environmental noise assessment, and even personal audio recording.

How do they work?

Sound meters use a microphone to pick up sound waves and convert them into electrical signals. These signals are then amplified and displayed on the meter’s screen. The units of measurement for SPL are decibels (dB). Most sound meters will have A-weighting applied to the measurements, which means that low and high frequencies are filtered out. This weighing scale is designed to more closely match how humans perceive loudness.

How to use a sound metre

Sound meters are relatively simple devices to use. First, you will need to select the mode you want to use. The most common modes are “peak” and “slow”. Peak mode measures very short bursts of sound, while slow mode gives a more accurate measurement of long-term exposure.

Once you have selected the mode, aim the meter at the source of the noise and press the “start” button. The sound meter will then take a measurement and display the results on the screen.

Type of sound metres

There are two main types of sound meters: analogue and digital. Analogue sound meters use a needle to indicate the SPL on a scale, while digital sound meters use a digital display. Both types of meters have their own advantages and disadvantages.

Analogue sound meters are typically more affordable than digital sound meters. However, they can be less accurate and more difficult to read.

Digital sound meters are usually more expensive, but they offer greater accuracy and are easier to read.

When choosing a sound meter, there are a few things you should keep in mind:

– The intended purpose of the device: Sound meters can be used for different purposes, such as industrial noise monitoring or personal audio recording. Make sure to choose a meter that is designed for your specific needs.

– The type of microphone: There are two main types of microphones used in sound meters: condenser and electret. Condenser microphones are more sensitive and accurate, but they also require power from a battery or external power source. Electret microphones are less expensive and don’t require an external power source, but they are not as sensitive or accurate.

– The frequency range: Sound meters can measure a wide range of frequencies, money by choosing a meter with a narrower frequency range.

– The accuracy: Sound meters can vary in their accuracy, with some models being more accurate than others. If precise measurements are important to you, make sure to choose a model with high accuracy.

Why you would need one

There are many reasons why you might need a sound meter. Maybe you work in an industrial environment and need to monitor noise levels. Or maybe you’re a musician who wants to make sure your recordings are of the highest quality. Whatever the reason, sound meters can be a valuable tool.

Price of a sound metre in the UK

Sound meters can vary in price depending on the features and accuracy. Basic models start at around £30, while more advanced models can cost over £100.


Sound meters are useful devices that can be used for a variety of purposes. If you need to measure sound levels, make sure to choose the right model for your needs and budget.
