Noise recognition on the iPhone: operating aid as a replacement for hearing

Anyone whose hearing is impaired or who walks around the world with headphones on may need some help in recognizing the auditory environment. From iOS 14, the Apple iPhone offers noise recognition as an operating aid. Using artificial intelligence, the audio signals of the environment are analyzed locally on the smartphone and a push message is triggered when selected noise sources are used. Various alarms, animals, household appliances and people can be set for noise detection on the iPhone as a replacement or aid to hearing. You will find out how to do this in this guide.

Operating help: Activate noise detection on the iPhone

If you want to activate the noise detection on the iPhone as an operating aid for everyday life or certain situations, then you can of course use the iOS settings. From iOS 14 you do the following on the Apple iPhone:

  1. Opens the Settings on the Apple smartphone
  2. Tap on the point Accessibility
  3. Select the item under "Hearing" Sound detection from
  4. Now activate the function with the "Noise detection" slider
  5. The point appears Sounds, with which you can activate certain noise sources
To activate the iPhone noise detection from iOS 14, go to Settings> Accessibility> Noise detection. You can read below which tones and noise sources you can choose.

Note: “Hey Siri” is deactivated when sound detection is activated. The voice command can then no longer be used to activate the Apple voice assistant Siri.

The Apple iPhone with iOS 14 can recognize these noises

If you have activated the noise detection on the iPhone, then - as shown in the last point of the list above - the option to select certain noise sources appears. For example, if your hearing is impaired or you are deaf, the following options can help you in everyday life or in certain situations:

  • Alarm: fire, siren, smoke
  • Animals: cat, dog
  • Household: household appliances, car horn, doorbell, door knock, running water
  • People: Baby cries

However, Apple gives the important note in the settings and in the Support document on the subject that noise detection is not a comprehensive protection. So you shouldn't rely on it if you could or are in dangerous situations (road traffic, etc.).

You shouldn't rely solely on your iPhone's sound detection when you're in a situation where you could be injured or harmed, or in high-risk or emergency situations, or when navigating.

    I find noise detection useless because it makes no sense at all because what's the point if you just have the noise detection because Siri can't do it, she can already hear it, but what's the point

      Sound detection is useful for deaf people. For example, they can find out when water is running or a window is smashed. I think that sounds reasonable.
