Hearing Aid

Real-time Hearing Aid & Amplifier is a smart sound amplification tool designed to help you hear clearer in your daily life. By leveraging low-latency audio processing algorithms, it captures environmental sounds through your phone's microphone, amplifies them, and streams them directly into your headphones. Whether you are in a noisy room, watching TV, attending a meeting, or having a face-to-face conversation, this app makes speech and ambient sounds easy to hear. 🌟 Key Features Powerful Real-time Amplification Experience continuous sound gain adjustment, allowing you to amplify surrounding sound up to 50.0x. Fine-tune the volume level using the intuitive gain slider to suit your environment. Treble Boost for Speech Clarity Turn on the speech clarity toggle to activate a high-pass audio filter. This algorithm reduces low-frequency background hums and amplifies frequency bands above 1.2 kHz, highlighting human speech so conversations become much easier to follow. Dynamic Waveform Visualizer Watch sound in real time! The app includes a responsive waveform visualizer that gives you immediate visual feedback on ambient volume and microphone capture. Background Service Support Keep hearing clearly even when your screen is locked or you are multitasking. The app runs as a high-priority foreground service with a persistent status bar notification. Acoustic Feedback Protection Protecting your hearing is our priority. The app detects your audio output routing and ensures playback only starts when headphones (Bluetooth or wired) are connected, preventing painful microphone-to-speaker feedback loops (howling). 📖 How to Use Connect Headphones: Connect your Bluetooth earphones or wired headset before starting the amplifier. Grant Permissions: Allow the app to access the "Microphone" to capture sound and "Bluetooth/Nearby Devices" to manage wireless headset routing. Start Amplifying: Tap the Power button to start the engine, and gradually adjust the gain slider to find your preferred listening volume.
