Welcome!

Acoustic warning signals of an electrical device, or any audible signal for that matter, are omnipresent in our everyday life and contribute to noise pollution. Only a few producers, however, have considered the effect, adequacy, and aesthetics of the sounds used. We aim to replace the ordinary (yet commonly used) piezo buzzers, which produce those annoying beeps.

About us

We are a dynamic team of musicologists, music psychologists, sound technicians and engineers led by Prof. Dr. Günther Rötter. We are already experienced in creating acoustic signals as designing a recess bell for a well-known opera and cooperating with Daimler AG for over than ten years proves.

Our aim

We want your business to gain competitive advantage over other competitors by producing suitable warning signals that live up to the quality of your products.

Gong Operahouse

Our proposal

We produce acoustic warning signals of all kinds that will meet the needs of your company/products. Warning signals that indicate imminent risk, for example, have to differ from warning signals that indicate the end of an operation. Prior to delivering, the effect of our warning signals will be tested by applying advanced procedures in musicology as well as empirical research.
