Picture yourself at a music concert, or a bar, or a party. The music, background conversations, or other sounds have gotten so loud that you can't even hear yourself think.

Exposure to loud noises is annoying and could damage your hearing. But how do you know if the surrounding noise in a certain place is actually loud enough to be hazardous to your health? Enter Apple's Noise app, courtesy of watchOS 6.

With the Noise app, you can check the ambient sounds to view the decibel level and determine if the noise is so loud as to be harmful to your hearing. You can also set a decibel threshold in the app and receive a notification if the surrounding noise reaches or exceeds that level.

The only drawback is that only Apple Watch Series 4 and Series 5£429 at Amazon UK running watchOS 6 support the Noise app. But if you have either device, you can set up the Noise app on your iPhone or directly on your watch. Let's try it both ways.

Set Up the Noise App on iPhone

On your iPhone, open the Watch app. In the My Watch section, tap the entry for Noise. Turn on the switch for Environmental Sound Measurements. This option uses the watch's microphone to measure and monitor sound levels throughout the day. Next, tap the option for Noise Notifications. Choose the decibel level at which you want to be warned if the sound around you gets too loud.

Set Up the Noise App on Apple Watch

The setup process works similarly on the Apple Watch. On your watch, open Settings and then tap the setting for Noise. Tap the option for Environmental Sound Measurements and then turn on the switch. Go back to the previous screen and tap the option for Noise Notifications. Select the decibel level at which you want to be notified if the noise around you gets too loud.

What Each Decibel Level Means

Looking at the different decibel levels, the top setting alerts you if the noise reaches 100 decibels, while the lowest setting alerts you at 80 decibels. Each setting also shows you how long you could listen to noise at this level on a daily basis before experiencing hearing loss.

By turning on Noise Notifications, you'll be alerted if the average sound level over three minutes reaches or exceeds the decibel level you selected. Apple breaks down the settings as follows:

  • 80 decibels: Around 5 hours and 30 minutes a day at this level can cause temporary hearing loss. The weekly limit at this level is 40 hours.
  • 85 decibels: Around 1 hour and 45 minutes a day at this level can cause temporary hearing loss. The weekly limit at this level is around 12 hours and 30 minutes.
  • 90 decibels: Around 30 minutes a day at this level can cause temporary hearing loss. The weekly limit at this level is 4 hours.
  • 95 decibels: Just 10 minutes a day at this level can cause temporary hearing loss. The weekly limit at this level is around 1 hour and 15 minutes.
  • 100 decibels: Even a few minutes a day at this level can cause temporary hearing loss. The weekly limit at this level is around 20 minutes.

How to Choose the Right Decibel Level

The level you choose depends on what you do and where you go during a typical day. You might want to try a higher level to start and then lower the level if you're not receiving any warnings and are still concerned about surrounding noise. Of course, you can also change the level based on your activities at a given time.

To do this, you'll want to view the settings both for decibels and duration. For example, if you're at a loud public event or concert that you know will last for a couple of hours, you'll want to set the decibels at a sufficient level so that you're alerted if and when the sound gets too loud.

You can always check the app at any time to get a reading on the current noise level and decide how to react. To do this, just open the app on your watch. The screen displays the current decibel level with a notice whether or not long-term exposure at this level could affect your hearing.

Tap the Learn More button to get additional information. The screen then explains the different decibel levels and their potential effects on your hearing.

Loud Environment Notifications

If the ambient sound reaches the decibel level you set, you'll receive a Loud Environment notification. The Noise app then shows you the number of decibels in the surrounding environment and issues a warning about hearing loss.

My Experience

I've been working for PCMag since early 2016 writing tutorials, how-to pieces, and other articles on consumer technology. Beyond PCMag, I've written news stories and tutorials for a variety of other websites and publications, including CNET, ZDNet, TechRepublic, Macworld, PC World, Time, US News & World Report, and AARP Magazine. I spent seven years writing breaking news for CNET as one of the site’s East Coast reporters. I've also written two books for Wiley & Sons—Windows 8: Five Minutes at a Time and Teach Yourself Visually LinkedIn.

My Areas of Expertise

I've used Windows, Office, and other Microsoft products for years so I'm well versed in that world. I also know the Mac quite well. I'm always working with iOS, iPadOS, watchOS, and Android on my various mobile devices. And these days, I write a lot about AI, so that's become another key area for me.

The Tech I Use

My wife always jokes about all the tech products we have around the house, but I manage to put them to good use for my articles. I like Lenovo computers, so I own a couple of Lenovo desktops and several laptops. I have three MacBooks and a Mac mini. For my mobile life and work, I use an iPhone 16 Pro, iPad Pro, and iPad mini as well as an Apple Watch. But since I write about Android, I own several Android phones and tablets. Like any tech person, I have a cabinet full of cables, wires, and assorted mysterious gadgets. And when it's time to take a break from writing, I have an old Xbox 360 and Nintendo Wii, both of which I use for exercise and fitness games.
