Rush_Hz_Plus is an Android app made for people with hearing loss. It listens for danger sounds in real time and sends haptic alerts you can feel. It uses on-device AI, so it works on the phone itself.
This app helps you notice sounds such as:
- Car horns
- Sirens
- Alarms
- Sudden loud impact sounds
- Other hazard sounds around you
It gives three levels of haptic alert, so you can tell how urgent the sound is.
Rush_Hz_Plus helps you stay aware of nearby hazards through vibration alerts.
Main features:
- Real-time sound detection
- Three-level haptic feedback
- On-device AI processing
- Fast response on Android phones
- Built for daily use
- Focused on accessibility for the hearing impaired
Because it runs on the device, it does not need a cloud server to detect sounds.
Use a phone or tablet with:
- Android 8.0 or later
- Microphone access
- Vibration support
- Enough free storage for the app
- A working speaker or quiet environment for better sound capture
For best use:
- Keep the device charged
- Allow microphone permission
- Place the phone where it can hear the room
- Turn on vibration mode
Visit the release page to download and run the app file:
After you open the page:
- Find the latest release

- Low alert: light vibration for mild sound activity
- Medium alert: stronger vibration for possible danger
- High alert: sharp vibration for urgent hazards
For the best result:
- Keep the phone in a pocket, bag, or on a table near you
- Use vibration mode
- Keep background noise low when possible

Rush_Hz_Plus was developed as a capstone project at Dongyang Mirae University. It focuses on accessibility and practical safety for daily life. The design keeps the app simple so non-technical users can install and use it with little setup
No, the app is made to run on the device itself for sound detection
It is built for real-time use. For best results, keep it open and let it access the microphone
Check that:
- Sound and vibration are turned on
- The device is not in silent mode with vibration off
- The app has permission to use vibration
- The phone case is not blocking vibration too much
Most modern Android devices should work if they support microphone input and vibration
