Apple watch OS 9.2 upgrades the hearing health function
Apple released the watchOS 9.2 operating system update this week to upgrade the hearing health function. When using wireless headphones with active noise reduction functions such as AirPods Pro 1st and 2nd generation, AirPods Max, Apple Watch’s “Noise” App The degree of ambient noise reduction is displayed.
Apple Watch users can also turn on notifications in the “Noise” app to receive reminders when the ambient noise level may affect hearing.
For example, the volume of a noisy restaurant is about 80 to 89 decibels. If the Apple Watch detects that the average volume in the vicinity exceeds 90 decibels for 3 minutes, the system will send a notification. According to the recommendations of the World Health Organization (WHO), the noise of 90 decibels should not be listened to for more than 30 minutes a day, and should not exceed 4 hours a week.
In addition, the “Health” app on the iPhone can track the user’s volume exposure for the past 1 hour, 1 day, 1 month, 6 months and 1 year, and will inform the user whether the headphone or ambient volume exceeds the World Health Organization recommended standard.
The hearing article of the “Health” app points out that sounds over 80 decibels are usually considered loud, and hearing will be affected by the size of the sound and the length of exposure. Even short-term exposure to very loud sounds can cause temporary hearing loss.
The Hearing Health Study conducted by Apple and the University of Michigan School of Public Health showed that 25% of the participants had an average daily ambient sound exposure exceeding the upper limit recommended by the World Health Organization; nearly 50% of the participants had worked in noisy places.
The study also pointed out that the average weekly headphone exposure of 1/10 participants exceeded the upper limit recommended by the World Health Organization. This means users should consider listening to music and other media at the lowest acceptable volume.
