What is HearAngel®?
HearAngel® is the best way for you and your family to listen to music without worrying about hearing damage. It’s an innovative app for your smartphone that monitors how you listen, and lets you know when you’re in danger of overexposure. It can also monitor your children’s listening habits and you can choose to set their listening levels and duration.
Why do you need HearAngel®?
We use headphones more and more in our daily lives, but if left unchecked this increased usage could have irreversible effects on our hearing.
Hearing damage can be caused by listening for long periods at quite moderate levels, or for quite short periods at high volume. HearAngel® is calibrated to your earpieces and so it knows just how loud you are listening and will advise you if you are in danger. If you wish, it can automatically adjust the sound level to keep you safe and has no effect on the sound quality.

It’s so easy to use HearAngel®. After you’ve downloaded the app, all you need to do is register your account, and select your earpiece details, and you’re good to go.
HearAngel® provides you with notifications to let you know what your current listening level is and keeps an eye on the length of time you have been listening, to let you know how close you are to reaching your daily limit. You’ll get a warning notification when you have used up a significant part of your DSA®.
When you use the auto mode, the sound level is automatically controlled for you, to make sure that your exposure to noise over time doesn’t go above hearing health guidelines. Remember that HearAngel® is working to ensure that your hearing dose over the entire day is safe, so it only makes small adjustments to the sound level.
You can look at your History page to review and monitor your listening, seeing in detail how long (time), how loud (volume) and what kind of music (energy) you’ve listened to.
Track it easily
HearAngel® is compatible with wearable technology, allowing you to monitor your listening with just a glance at your wrist.
How the app works
Hearing damage can be caused by listening for long periods at quite moderate levels, or for quite short periods at high volume. It is a complex combination of listening period (time), how loud you listen (volume) and the energy content (density) of the sound you listen to that creates the “dose” of sound that does the damage.
Speech typically has a low energy, because of the pauses between words but Electronic Dance Music, which is usually highly compressed dynamically will have a MUCH higher energy for the same peak to peak listening level.
Everyone has a Daily Sound Allowance (DSA®). The Health and Safety Executive recommend a maximum of 85dBA (average level) in an 8 hour period. This means that the level can be louder for some of the time, if it is also quieter sometimes – e.g. when you’re not listening.
Until now, there has been no way that your sound dose can be calculated outside of a laboratory. HearAngel® is calibrated to your earpieces; it knows just how loud you are listening. It can give you accurate information about your listening habits and will notify you if you are in danger. If you wish, it can automatically adjust the sound level to keep you safe and has no effect on the sound quality.
To safeguard your children’s hearing, HearAngel® includes a parental mode which lets you set your own values for Peak Level, DSA® use and even listening time duration for selected apps on your children’s phones and lock these values behind a password.
HearAngel® never lets you exceed your DSA® and prevents you from being exposed to harmful levels of sound.
A little more about us
HearAngel is developed by LimitEar, a company formed 8 years ago to develop hearing dose management technologies for professional headphone users. The company’s technologies, HDM®Pro, and LimitEar-FL™protect users in line with Noise at Work Regulations. They have been selected for use in military, live events and broadcast applications. The company has contracts with Sennheiser and Meridian/ACS and has collaborated with Racal Esterline to be used in a new aviation headset.
“This innovative product will assist users in managing their exposure to reproduced sound and help protect themselves against avoidable noise induced hearing loss.”
“I take great care of my hearing as I know how important yet fragile it is. HearAngel® will enable consumers to have the same protection that we have and help them to protect themselves.”
“I see far too many young people with avoidable hearing loss. By providing information and protection, HearAngel® will enable them to make informed decisions.”
“The Noise Abatement Society runs the Love your Ears™ campaign to increase the awareness of the risks of prolonged headphone use – listening too loudly for too long. Up to now it has been difficult for a recreational headphone user to know what their exposure level is and, consequently, risk of hearing impairment or loss. With the introduction of HearAngel® they now have access to accurate information and protection in accordance with hearing health recommendations from regulators.”
