Subjective Assessment by Digital Noise Files

You send us a digital noise file with a short, as precisely described as possible, which noise event disturbs you. With variable speed fan/blower, it should ideally be a speed built-up including the speed signal. Using high-quality audio technology, we hear/analyze your noise that provides us an overview of the noise situation. Based on our many years of experience, we first subjectively classify the noise and determine possible sources. As a result, we then define the analysis method.
