Title: Xueqin Zha: Innovator in Sound Absorption Technologies

Introduction

Xueqin Zha is a notable inventor based in Böblingen, Germany. He has made significant contributions to the field of sound absorption technologies, holding a total of 3 patents. His innovative work focuses on creating solutions that enhance acoustic performance in various environments.

Latest Patents

Zha's latest patents include groundbreaking inventions such as structured molded parts for sound absorption. These structured pre-form bodies serve as panel linings for wide-band sound absorption, utilizing an open-cell foam material with a rigid framework that co-vibrates in a resonant manner at low frequencies. The design features a base layer and a columnar structure that is strategically positioned to optimize sound absorption. The columnar structure's non-symmetrical distribution of height and cross-section creates a wide-band tuned moderator gap, enhancing its effectiveness.

Another significant patent is for an anechoic room designed for the entire auditory range. This low reverberating room is particularly effective for low-frequency ranges below 100 Hz. The walls and ceiling are covered with sound absorbers that occupy approximately 70-90% of the room's surface area, excluding the floor. These sound absorbers are constructed with multiple layers and feature a closed, plane but acoustically permeable surface. They incorporate inside plates made of metal or heavy foil, designed with varying thicknesses to absorb sound across different frequency ranges.
