Heat pump and recuperator nvh engineering

I have made some nvh improvements on heat pumps and on recuperators. I had first performance in front of camera in construction video blog. 
Recently, I have been working with Polish brands IzziFast and reQnet.

Our goal is to reduce the sound level emitted from these devices.
Pumps are devices standing outside the building, recuperators inside.
Thanks to minor modifications to the duty points, we have reduced the noise level of the pumps by approximately 1.5 dB(A) without compromising the performance and efficiency.

The IzziFast brand runs its own Vlog.
I had the pleasure of being recorded during a conversation with the designer Tomek Górny during the first measurement sessions. My first performance in front of the camera was not bad for me.
The next ones will be much better.

Please watch the video and leave comments.

Noisehacking is my slogan

When coming up with the term ‘Noisehacking’, I was referring to the term Biohacking. Biohacking and noisehacking are two different approaches to optimising our lives in different areas. The slogan also perfectly sums up the type of some of the features in the music in the meditation and development app Focusly that I have been working on.

Vibroacoustic engineering in automotive

Global organizations are forcing the construction of increasingly fuel-efficient cars, reducing the consumption of natural resources. Usually meeting such requirements leads to optimization of car design. Very often it concerns the generation of noise, which can sometimes be a nuisance when driving a car.

Noise becomes a real problem for the end customer and is cascaded by car corporations throughout the supply chain. As a result, OEMs are changing their cars, and suppliers and sub-suppliers must also follow developments imposed from above.
