  • Patent number: 10986444
    Abstract: Techniques for simulating a microphone array and generating synthetic audio data to analyze the microphone array geometry. This reduces the development cost of new microphone arrays by enabling an evaluation of performance metrics (False Rejection Rate (FRR), Word Error Rate (WER), etc.) without building device hardware or collecting data. To generate the synthetic audio data, the system performs acoustic modeling to determine a room impulse response associated with a prototype device (e.g., potential microphone array) in a room. The acoustic modeling is based on two parameters—a device response (information about acoustics and geometry of the prototype device) and a room response (information about acoustics and geometry of the room). The device response can be simulated based on the microphone array geometry, and the room response can be determined using a specialized microphone and a plane wave decomposition algorithm.

  • Patent number: 10979833
    Abstract: An acoustical performance evaluation method includes a reference sound pressure decision step and a deviation calculation step. In the reference sound pressure decision step, frequency response of sound pressure level, obtained by considering only an influence of a first factor of a plurality of factors causing a deterioration in frequency response of sound pressure level of a loudspeaker to be evaluated, are decided as a reference sound pressure. The reference sound pressure is frequency response of sound pressure level of the loudspeaker in the anechoic chamber calculated through a simulation or measured through a measurement experiment. In the deviation calculation step, a deviation between the reference sound pressure and a target sound pressure is calculated as an evaluation index of acoustical performance. The target sound pressure is frequency response of sound pressure level of the loudspeaker in the anechoic chamber calculated through a simulation or measured through a measurement experiment.
