Reverberation Time TRIZ Cases
- Voice-Controlled Electronic Apparatus Placement Using Reverberation Time
By measuring reverberation time across candidate locations, the apparatus finds a better placement for more accurate voice command recognition.
- Adaptive Noise Control Using Listener Location and Acoustic Response
Listener position and local acoustic response are used to adjust noise control parameters as conditions change, improving audio quality and comfort.
- Real-Time Audio Rendering with Position-Aware Room Simulation
Precomputed room acoustics and UWB user positioning maintain audio quality across positions without repeated recalibration.
- Audio Distance Rendering Adjusting Gain and Correlation
Distance rendering adjusts gain and binaural correlation to preserve spatial characteristics when user-to-source distance changes.
- Real-Time Room Acoustic Impulse Response Calculation
Dynamic signal evaluation filters interfering noise to calculate room acoustic impulse responses, extending measurement capabilities for large spaces.
- Two-Channel Room Transfer Function Estimation Using Spectral Splitting
A two-channel sound calibration system uses spectral splitting to generate uncorrelated signals for simultaneous playback and recording.
- Sound Production Apparatus for Virtual Space Acoustic Simulation
A sound production apparatus synthesizes reproduction sounds using late reverberation settings and object characteristics.
- Room Mode Control via Active Cancellation Signal
Deriving a cancelling signal from the system impulse response reduces acoustic resonance energy without requiring separate hardware.
- Voice Model Transfer Across Devices
A user-dependent audio model identifies speakers across multiple computing systems without individual device training.
- Omnidirectional Sound Source Device with Radial Longitudinal Propagation
A sound source device guides acoustic waves radially and longitudinally through an annular emission area to achieve high omnidirectionality.
