A hearing assistance and/or noise suppression device leverages computing power of an external device with a digital signal processor, such as a special unit that is configured to communicate with a smart device (e.g., a smart phone, smart watch or smart pendant) or a smart phone with a digital signal processor. Methods include having a hearing transducer communicate with and offload computing tasks to an external device with a digital signal processor. Systems include a hearing transducer with transducer circuitry that receives, amplifies and outputs digital signal processed audio from another device. Methods provide self-adjustment and fitting through a touch screen interface, which can be conducted outside of a clinical setting in a real world environment, and method can include remote data collection and communications with clinicians.

A sound processing apparatus includes a first microphone which acquires environmental sound, a second microphone which acquires sound of a noise source, and a CPU which causes the sound processing apparatus to function as a noise detection unit configured to generate a noise signal of the noise source according to a sound signal from the second microphone, the noise detection unit reducing sound other than noise of the noise source from the sound signal from the second microphone and generating the noise signal, and a noise reducing unit configured to reduce the noise of the noise included in a sound signal from the first microphone using the sound signal from the noise detection unit.

An audio signal processing circuit includes a filter, a gain control circuit, and a bass boost circuit. The filter filters an audio signal and produces a filtered signal accordingly. The gain control circuit divides the filtered signal in the time domain into a first segment and a second segment that are substantially equal in length, measures a first amplitude of the first segment and a second amplitude of the second segment, and generates a gain based on the first amplitude which is greater than the second amplitude. The bass boost circuit adjusts the amplitudes of the first segment and the second segment according to the gain.

An electronic device whose enclosure or housing panel is used as part of an acoustic system is described. The panel is divided into several sub-panels. For each sub-panel, the device includes one or more actuators attached to vibrate the sub-panel. The actuator and its attached sub-panel convert an audio signal to acoustic output. Each actuator and sub-panel combination may receive a separate audio signal. The device includes a digital signal processor for controlling each of the sub-panel driving audio signals. The device may further include one or more backing frames that are attached to the panel to provide boundary conditions to the sub-panels. The boundary conditions define a resonance frequency for each sub-panel.

The hearing loss correction system comprises a microphone unit, a speaker unit and a mobile phone inbuilt application processor to operatively connect the microphone unit with the speaker unit for recording environmental sound signal though the microphone unit and storage free direct streaming of said recorded sound signal to the speaker unit upon real time amplification and background noise suppression.

A technology is provided that can obtain two audio data with reduced noise, in a system including independent recording devices. A first frequency analyzer performs first frequency analysis on first audio data for each analysis range and generates first result information indicating the result of the first frequency analysis for each analysis range. A condition determinator determines the analysis range based on a first audio quality of the first audio data. A noise band detector detects a noise band for each analysis range based on the first result information and second result information. A first filter processor generates a first filter for filtering data of a noise band for each analysis range, applies a first filter process by the first filter on first audio data for each analysis range, and generates third audio data.
