Hp Senior Acoustic Engineer with 7–10 years experience designing and optimizing acoustic systems for video conferencing products. Responsible for developing microphone arrays, beamforming, echo cancellation, and audio performance tuning.
Responsibilities
Design and optimize acoustic systems for video conferencing devices, including microphones, loudspeakers, and audio signal paths.
Develop and tune microphone arrays, beamforming, sound source localization (SSL), and talker detection algorithms.
Analyze and optimize acoustic echo cancellation (AEC), noise reduction, dereverberation, automatic gain control, and other audio processing algorithms.
Perform acoustic measurements and characterize microphone and loudspeaker performance using laboratory equipment and industry-standard methodologies.
Develop acoustic test plans, measurement methodologies, and performance criteria for product development and certification.
Investigate and resolve audio quality issues such as echo, feedback, distortion, reverberation, noise, coloration, and poor speech intelligibility.
Analyze frequency response, polar patterns, directivity, SNR, THD, sensitivity, latency, and other acoustic/audio performance metrics.
Work closely with mechanical engineers on microphone and speaker placement, enclosure design, acoustic isolation, vibration coupling, and airflow/noise issues.
Collaborate with DSP/software engineers to develop, integrate, tune, and validate real-time audio processing algorithms.
Develop simulation and data-analysis tools using Python, MATLAB, or similar tools.
Conduct subjective listening tests and correlate objective acoustic measurements with perceived audio quality.
Support product bring-up, debugging, certification, and production validation.
