EarMachine is an app that makes it easy to listen to the sounds that you want to hear. Those sounds can be picked up by the microphone in your phone or earbuds, and can be played from your music library! EarMachine is helpful in situations ranging from talking in noisy restaurants to watching television at home. This work is funded by the National Institutes of Health (of the United States of America). Features: Simple Interface, Complex Processing With a simple interface, EarMachine, allows you to adjust more that 150 signal processing parameters with a simple swipe of your finger on a wheel. The mapping from wheel position to parameter values is the result of a large-scale analysis of the hearing status of more than 10,000 people. EarShare: An intelligent recommendation engine Ear Machine also contains a recommendation engine called EarShare. This engine will listen to the sounds around you and use that information to recommend wheel positions. The recommendations are based on both large-scale analyses of hearing abilities as well as your usage of the app. EarShare will give better recommendations the more you use the app. Listen to whatever sounds you want. Ear Machine allows you to choose whether you want to listen to the microphone in your iOS device, or the one in your earbuds (iOS 7 only). You can also use Ear Machine to listen to songs/podcasts in your music library. State of the Art Signal Processing The signal processing in Ear Machine is similar to what is used in most hearing instruments. A wide-dynamic range multiband compressor ensures that quiet sounds are amplified, while protecting you from sounds that are already loud. A multiband limiter provides further protection from loud sounds. An expander makes sure that very quiet sounds (e.g., refrigerator hum) are not annoying. You can even use Ear Machine as a sound level meter (works best with phone microphone). ## Key features - Microphone and earbud audio input - Music library playback - Advanced signal processing - Intelligent recommendation engine (EarShare) - Customizable parameter adjustments - Sound level meter functionality ## Recent user reviews (10 of 50) All indexed reviews: https://appshunter.io/ios/app/earmachine/id732177210/reviews.md ### 1/5 — Doesn’t load any more *2022-12-06, version 1.2.2* This app is no good. The app support is not supported either. Don’t bother trying it. ### 1/5 — Unusable *2022-11-26, version 1.2.2* Downloaded this to preview it for a family member who has partial hearing loss. I’m not sure if the App Store has the correct version but what I received is totally unusable. The sounds are garbled and strange and normal voices sound like they are being spoken by a robot. ### 4/5 — What happened? Doesn’t work with IOS 16.1.1 *2022-11-18, version 1.2.2* I’ve relied on this app and enjoyed for years - then my iPhone updated to IOS 16.1.1 overnight and poof,… the use of the internal phone mic is gone. I checked the mic using voice memo and yes it does work fine. Something about the 16.1.1 update has caused a disconnect. When will this bug be fixed? ### 5/5 — Easy to use! *2022-11-07, version 1.2.2* It's amazing with all the customisation it's really good ### 4/5 — Works better than my expensive hearing aid *2022-11-01, version 1.2.2* My Signia hearing aid makes everything loud but I can't understand words. With this app I can watch television and understand everything. Amazing. Thank you! The stress of following conversation is gone. ### 1/5 — Ear Machine does not support airpods *2022-03-23, version 1.2.2* Ear Machine fails using air pods seems you have to use wired Apple Earbuds useless application given this limitation ### 1/5 — Almost destroyed my ears *2022-03-20, version 1.2.2* I opened this app with a volume of 1, I plugged in headphones because it needs headphones to work, and I slightly increased the loudness and the app automatically turned my iPad volume to 100% and it gave me a heart attack ### 1/5 — App will not connect to Apple ear buds. *2022-03-08, version 1.2.2* This app works with only wire ear buds, it will not connect when I have wireless Apple ear buds in and on. ### 3/5 — Bad sound *2022-02-23, version 1.2.2* It works while watching TV but has bad crackling sound. I’m going to look for something better ### 1/5 — Non-starter w/o retro wired Apple earpods *2021-07-04, version 1.2.2* I use bluetoof earpods, by JLabs, not Apple. A deadstop right there. I dont own wired anymore ## Frequently asked questions about EarMachine ### What does EarMachine do?
