This presentation will report on an acoustical engineering internship that was completed with and supervised by the American acoustical consulting and engineering company Brooks Acoustics Corporation (BAC) in Pompano Beach, Florida. Since 1992, the BAC team has contributed to over 1,100 national and international projects and actively participates in the academic, standards and professional communities […]

There are several standardized methods for characterizing the reflection properties of materials, such as the classic reverberation chamber method and the impedance tube method. For practical application, some alternative in-situ methods have been developed in recent years. However, all these methods to determine the reflection factor can lack robustness and reliability. In this report, a […]

During the internship at GoerTek Inc., the focus was primarily on the analysis and optimization of acoustic systems for “True Wireless Stereo Earbuds”, so-called TWS devices. The main responsibilities included conducting both subjective and objective tests based on acoustic performance, evaluating products through metrics such as frequency response curves, distortion curves, and manual listening tests.
