Put on some Bluetooth headphones, tap the center button, and you can hear and amplify what your phone's microphone is picking up. It's also possible to set up an automatic noise-trigger for audio recordings and have them sent to your email. Whether you want to responsibly audio-monitor your environment, hear the TV and conversations better (non-medical hearing aid), or just listen to birdsong from indoors, Ear Scout amplifies and streams the audio from the mic to your Bluetooth headset (mic-to-headphone) in real time for remote hearing. HEADPHONES REQUIRED. To avoid audio feedback you need to use headphones. SAFETY FEATURE. After starting the app the volume increases gently to the set level. This way you have time to adjust to high gain settings from the previous session. REVIEWS: Please review the app if you try it. Ear Scout amplifies sound coming from your phone's microphone straight to your earphones (direct mic-to-headphones audio). To fine-tune the incoming signal, use the audio equalizer. DISCLAIMER. This app is for remote hearing via email / Bluetooth (e.g. listening to nature / property monitoring) and sound amplification (non-medical hearing aid), not to listen in on private conversations. Please use Ear Scout responsibly. Don't forget to leave a review.
