How To Set A Volume Limit On Iphone

Did you know that listening to headphones or earbuds at loud levels tin harm your hearing over time? The threshold for injury is based on a combination of how loud you lot listen and for how long.

If you're in a noisy surround similar a train or aeroplane, information technology's like shooting fish in a barrel to inadvertently plough upwardly the book above condom levels. If you listen to headphones a lot, particularly in such environments, you lot could be putting your ears in danger. Excessive volume over fourth dimension can injure the hair cells in your ears — which are critical for your hearing — and is irreversible. Damage plenty hair cells, and yous'll kickoff to permanently impair your hearing.

Fortunately, if you've got an iPhone^®, you can use its Headphone Safe features to assistance preserve your hearing. In this article, nosotros'll describe what information technology is, and how to access information technology.

Hearing Is Not Linear

Human hearing is sensitive to a wide range of sounds. We can hear something equally quiet equally the rustle of a leafage or as loud equally a jet taking off — and everything in-between.

To quantify such a wide range of sonic energy (referred to every bit sound pressure level or SPL for short), scientists and audio professionals use the decibel (dB) calibration, which is logarithmic rather than linear. Raising the level past 3dB doubles the energy of a sound; raising it by 10dB increases information technology by a cistron of 10; raising information technology by 20dB past a cistron of 100.

With that in mind, hither's a listing of mutual sound levels, sourced from a document published by the Centers for Affliction Command (CDC) :

Mobile devices typically output music at up to well-nigh 110dB SPL, just annihilation over 85dB is considered dangerous. The longer you listen at unsafe levels, the more than probable that hearing loss will occur, and the higher the SPL, the shorter the fourth dimension in which that damage tin can happen. For example, impairment can occur after viii hours at 85dB, after two hours at 91dB, subsequently 30 minutes at 97dB and subsequently just 15 minutes at 100dB.

The lesser line is this: Whether you lot're concerned well-nigh your long-term hearing safe or that of your child, or even if you merely have sensitive ears, setting volume limits and monitoring your time of exposure is a skilful idea.

Your iPhone to the Rescue

Fortunately, the iPhone has an internal signal processor called a limiter, which allows you to set a book threshold to a higher place which sound can't get. Whatever audio that tries to exceed the threshold has its level automatically reduced — in layman's terms, the signal is "squashed down."

Even if yous don't use the limiter, your iPhone can rail your exposure to sound through headphones over time, and you even have it notify you if you've exceeded safe limits. To make all of this work, you demand to configure things correctly in your iPhone settings.

Setting Up Headphone Rubber

To access the Headphone Safe features on an iPhone, follow these simple steps:

1. Open Settings.

2. Tap either Sounds or Sounds & Haptics, depending on your iPhone model.

two. Tap Headphone Prophylactic:

three. In the Headphone Safety screen (shown below), turn on Reduce Loud Sounds and set the limiter. If you mind less than eight hours a day, yous tin can continue it at 85 decibels. Otherwise, plow it downward to 80 decibels.

4. In that aforementioned screen, plough on Headphone Notifications so that you'll get a warning if you mind too loud for likewise long over a 7-twenty-four hours period.

Track It

Your iPhone keeps track of your exposure to loud sounds over time through the built-in Apple Health app. If you lot want to meet how much exposure you've had over the concluding calendar week, it's easy:

i. Open the Wellness App.

2. Tap the Browse button at the bottom correct.

3. Tap Hearing:

iv. Tap Headphone Sound Levels:

On the Headphone Sound Levels page, you'll run across your exposure for the calendar week in decibels and whether yous've exceeded salubrious levels:

More Solutions

We've focused here on the iPhone'southward Headphone Safety features, simply Android™ phones also offer a like limiting function. Chosen Media Volume Limits, it too lets y'all set a maximum audio level for listening on headphones.

Yamaha has tackled the issue of safe levels differently. Its newest wireless headphones and earbuds characteristic Listening Intendance technology , which allows the user to hear the music clearly at lower volumes. Humans hear midrange frequencies louder than lows or highs. Because of that, people tend to turn upwardly the volume to better hear the bass and treble elements. Listening Care compensates for that past using equalization (frequency changes) to automatically brand sure that you're hearing an fifty-fifty tonal balance at any volume.

Listening Care is even more sophisticated on products like the Yamaha EP-E70A earphones or YH-E700A headphones. Those models factor in not only the level of the music you're listening to, but also the amount of background noise around you to create the ultimate tonal settings.

Employ the Tech

Whether it'due south Headphone Safety on iOS, Media Volume Limits on Android or Yamaha Listening Care, technical solutions are available to aid you preserve your hearing when listening on headphones or earbuds. Have advantage of these sophisticated technologies so you can enjoy your music worry-free.

It's also a adept thought to go a hearing exam. Non only will that show any bug you might take now, but information technology will serve equally a practiced baseline to compare to when you become future tests.
