Title: Rolf Helber: Innovator in Acoustical Engineering
Introduction
Rolf Helber is a notable inventor based in Schorndorf, Germany. He has made significant contributions to the field of acoustical engineering, holding a total of 4 patents. His work focuses on methods and devices that enhance the understanding and management of sound in various applications.
Latest Patents
One of Rolf Helber's latest patents is a method and device for determining acoustical transfer impedance. This innovative method involves generating an acoustical volume velocity Q at a listening position, measuring a response quantity p, such as sound or vibration, at a suspected source position, and determining the acoustical transfer impedance Z as the response quantity p divided by the acoustical volume velocity Q, expressed as Z=p/Q. The invention utilizes a simulator that mimics the acoustic properties of a human head, incorporating a simulated human ear with an orifice and a sound source to output the acoustical volume velocity Q. The output volume velocity Q is estimated using measurements from two microphones placed inside the corresponding ear canal.
Another significant patent by Helber is a device for noise structuring in a motor vehicle. This device features multiple gas-carrying lines connected to an internal combustion engine, with at least two of these lines acoustically linked by one or more connections. This innovation aims to improve the acoustic performance of vehicles, enhancing the driving experience.
