Measure Sound Better
Headphone Noise Floor Test System
Overview
Due to the homogenization of features in TWS (True Wireless Stereo) headphone, competition among them is becoming increasingly fierce. Users are no longer satisfied with battery life and ANC (Active Noise Cancellation) features; they now seek solutions to address issues of low current sound and noise floor. Meeting this requirement has become key to satisfying customers.
Recognizing the importance of noise floor control, well-known headphone brands have identified the need for effective solutions. However, traditional equipment and algorithms have limitations in meeting the demands of modern noise floor testing. To tackle this challenge, CRYSOUND has developed a low-noise ear simulator, along with compatible algorithms and an appropriate testing environment.
