Even when you are organizing a party at home, it is worth checking to see if the sound level is within acceptable limits. You don’t have to buy a special device to do this – just your smartphone, which you use every day.

Various applications have been developed for smartphones that can use built-in sensors to measure the sound of your environment, for example, 11 Best Decibel Meter Apps for Android & iOS. We have also found 9 free sound level apps for Android & iOS for you.

Sound Meter – Decibel meter & Noise meter

sound meter decibel meterIf you want to measure whether the noise data from the manufacturers is correct, you can use the Sound Meter application. It shows you close to real values, which you will get even if you measure sound with a special device.

The app shows you the current value of the noise that surrounds you (more precisely, your smartphone). For your convenience, you can change the color scheme of the app by changing a dark theme to a light one and vice versa.

For each device, the Sound Meter can be calibrated for more accurate measurements and indicators. If you know the exact level of noise in a particular environment, you can simply enter this value into the Sound Meter and the sensors will automatically calibrate.

For easy use, the application can be converted to a compact interface that does not take up the entire screen. Determine the ambient sound value right now – in your apartment, car, or house. This way, you can protect your hearing from damage.

Decibel Meter (Sound Meter)

decibel meter sound meterIf you are using an Apple device and want to know what sound level is around you at the moment, you can use the Decibel Meter app. Decibel Meter measures ambient volume in decibels, which is the most common unit of sound measurement.

The loudness of the environment around you can be devastating to people’s hearing – so you should check this fact and if there is indeed a danger, try to avoid it.

On the screen, after starting the Decibel Meter and measuring, you will see a circular scale on which the sound level is marked. The scale also indicates which area you are in at the moment and whether you are surrounded by silence, speech, noise, or even dangerous loud sounds.

Below you can explore the time scale of the volume – whether the noise is quiet at the moment, or whether it is still rising. The Decibel Meter settings are very sensitive and allow you to calibrate your measurements even slightly – especially if you have a real sound level meter at hand.

Sound Meter Simple Detector

sound meter simple detectorSound Meter Simple Detector is a simple enough application in terms of interface and functionality. In just one measurement the application will give you information about the sound indicators in a certain room, and you can also clearly see the level.

Sound Meter Simple Detector uses a built-in sound sensor on your smartphone. It is worth noting that such sensors measure noise all the time when testing speakers and microphones, but users do not have this built-in feature.

As well as displaying numbers on the screen, there is also a sound color scale. It varies from yellow to red, depending on the volume. You will also see brief information about which room or event has a similar sound level.

For example, Sound Meter Simple Detector 20 dB is almost perfect silence, and 80 dB corresponds to a noisy and busy street. According to user feedback, this tool defines the environmental indicators quite accurately.

Sound Analyzer App

sound analyzer appIf you need 2 modes of operation – noise level measurement (SLM) and real-time sound level analysis (RTA) – the Sound Analyzer App is a perfect choice. The application has no ads, as well as no paid features that you will have to pay for constantly.

The noise that occurs around you, Sound Analyzer App quickly measures and displays the data for you. The entire analysis is available in graphs that clearly show how the sound is changing over time, as well as other sound indicators.

The sound pressure indicators in the Sound Analyzer App require separate adjustments. If you’ve never seen such devices or indicators before, simply set the default data. Of course, it won’t give you perfectly accurate results, but you’ll know the approximate values.

Settings and calibration are set each time you are going to start measuring – which is not the most convenient solution. Yet, there’s no denying that the Sound Analyzer App is one of the few applications that weighs noise according to time parameters.

Decibel Meter – Sound Meter

decibel meter sound meter google playThis application works with a microphone, so Decibel Meter will ask you to access it during its installation. The developers guarantee that the microphone will only be used while the application is running and will not record your conversations.

With the help of data received from the microphone, Decibel Meter determines the sound level and vibration, and can also calculate several other characteristics. Before you can start using the application, you will need to calibrate your phone a little.

Decibel Meter can also determine what the maximum and minimum noise levels were during the entire measurement period. The values are read by the microphone recording, the duration of which you adjust yourself. You can stop the measurements at any time.

It is also worth noting that calibration can take place in 2 modes: manual if you have a real noise meter, or automatic. In automatic mode, Decibel Meter adjusts itself to the characteristics of your smartphone and makes measurements according to them.

Sound Meter: decibel meter, noise detector

sound meter decibel meter noise detectorThe sound around you is easy to measure and also to determine if it is dangerous to your hearing. The Sound Meter application does a good job of this. It uses a telephone microphone to obtain environmental noise data and can also measure pressure levels.

It is worth noting that the readings obtained with your smartphone’s microphone may be inaccurate. All devices are designed for the sound of the human voice, and the noise levels above 90 dB may simply not be perceived by the microphone.

Sound Meter can be used to measure too noisy sounds around you. This can help avoid high decibels that can hurt you. Maximum, average, and minimum noise values are detected during the measurement.

So, for example, you can measure with a Sound Meter in different parts of the apartment. The values are shown on a graph for easy visual perception. The calculated sound value in decibels is always shown on the home screen.
