Virtual event: Bosch Home Comfort Group ExpertTalk SOUND
At the Bosch Home Comfort Group's online expert discussion, sound experts Alexander Merzkirch and Jürgen Herbst explain how heat pumps are really becoming quieter and what progress has already been made in noise avoidance in recent years.
When is quiet quiet enough? – Sound experts Alexander Merzkirch and Jürgen Herbst from the Bosch Home Comfort Group answered this question in the ExpertTalk SOUND as an informative virtual event. In their presentations, Merzkirch and Herbst highlighted current developments and challenges in the noise reduction of heat pumps in the context of current European legislation and noise protection regulations.
The two experts vividly demonstrated the progress that has already been made in noise avoidance and presented the latest results of psychoacoustic investigations as well as the development of new tools for simulating and reducing noise at the Bosch Home Comfort Group. This includes modern noise reduction measures, improved component selection and novel visualization techniques - always with the aim of making the heat pumps quieter and at the same time more pleasant for the ears of the end users.
A key message of the event: The reduction of sound power by up to 15 dB in the last five years means that heat pumps in purely residential areas can now be operated almost silently. For example, most modern heat pumps from the Bosch Home Comfort Group brand portfolio achieve a sound output of less than 50 dB(A) in night mode. The Bosch Home Comfort Group is committed to the further development of quiet and efficient solutions that can also be integrated into existing buildings and at the same time meet legal requirements. The two heat pump professionals made it clear that the topic of psychoacoustics is playing an increasingly important role in development. Targeted noise management and the use of psychoacoustic models not only achieve measurable values, but also optimize the subjective perception of sound. Following the online event, numerous questions from the expert audience could be answered directly. A recording and the slides of the ExpertTalk SOUND are available for download here.
