How to Measure the Decibels on iPhone

Ever wondered how loud the music playing in your headphones or your ambiance is? Loud noises aren’t safe for our ears for too long. But how do you know if the noise is too loud to impact your hearing health? Worry not; read along as we share how to measure decibels on iPhone to check the noise level around you.

Being aware of the noise level can help if you are trying to create a quiet environment to study, work, or shoot a video. Besides, anything beyond 120 dB can instantly damage your ears. Fortunately, your iPhone can measure the noise levels without fancy equipment. Let’s dive in and learn how.

Use a Third-Party App to Measure the Ambient Noise Level
Instead of getting exposed to unregulated noise, measure the decibel level of your ambiance on your iPhone. Your iPhone doesn’t have an app to measure external noise levels; hence, you can get help from a third-party app on the App Store. Here’s how to do it.

Tip: In general, exposure to any sound that measures 70 dB or more for a prolonged period can potentially harm your ears. Hence, while trying to measure noise levels, you should avoid such ambiance with loud noises.

Step 1: Open the App Store, go to the search tab, and tap the Search bar.

Step 2: Search for ‘decibel meter’ and tap Get to download the app from the results.

Alternatively, download the app using the below App Store link and skip to step 4.

Step 4: Once the app is installed, tap Open.

Step 5: Tap Start.

Step 6: Since the app has been newly installed on your iPhone, give the mic permissions. Tap Allow.

Step 7: Once you’re done measuring the noise levels, tap Reset. And that’s it.

Measure Headphone Decibel Level on iPhone
Like external noise levels, listening to loud music on your iPhone via wired or wireless headphones can also damage your ears. Fortunately, your iPhone has a hearing tool that lets you check/measure the decibel level on your iPhone from the Control Center while listening via headphones (wired or wireless). Here’s how to enable and access it.

1. For AirPods
If you are trying to measure the noise levels of the audio through your AirPods, follow these steps.

Step 1: Launch the Settings on your iPhone and tap Control Center.

Step 2: Tap and add the Hearing control to the Control Center of your iPhone.

Step 3: Tap the back (>) button at the top left to go back.

Now, connect your AirPods to your iPhone, play any music, and follow along.

Step 4: Go to the home screen of your iPhone and swipe down from the top-right corner of the screen to access the Control Center.

Step 5: Tap the Hearing control (ear-shaped icon) from the Control Center to expand it and view the live decibel level of the music being played in your ears via your AirPods.

Note: If the volume is below 80 dB, it will show the dB level in green, which means it’s healthy for your ears. But if you’re listening to loud music, i.e., more than 80 dB, it will show an exclamation warning in orange, meaning you should lower the volume to keep your ears safe.

Here’s a sample of what safe vs. unsafe sounds look like from the Control Center of your iPhone.
