I measured the noise level of a fridge in a bedsit

I was recently commissioned to measure the noise of a Refrigerator. A few years ago I myself had to deal with a noisy fridge in a bedsit. I couldn't sleep and was tired in the morning. Nowadays, I appreciate acoustic comfort and silence, so I would definitely check what the noise level of a new fridge is in my bedroom 😊.

☃️ Not all fridges are the same when it comes to noise. In fact, the difference in sound level can make a significant difference to your quality of sleep, especially if you live in a bedsit and the fridge is close by.

👉 I was commissioned to measure the noise of a fridge and relate this to the specifications of the white goods and the overall assessment of the situation. A client in a rented flat is having trouble sleeping because the fridge is noisy.

📈 The results were as follows:
– The noise level of the fridge was approximately 35-40 dB(A),
– When the fridge was switched off, the level dropped to 27-29 dB(A),
– The sound background in the flat when all appliances were switched off was around 20 dB(A),
– The technical specification of the fridge indicated a noise level of 40 dB.

👩‍💻 The client is absolutely right that this particular fridge is noisy and this can cause sleep problems. Getting used to this level of noise is not really a satisfactory solution. There are now very quiet fridges on the market, reaching as low as 30 dB, although of course this usually comes with a higher price tag.

📰 In my article for Focusly (link) I discussed a similar situation.

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.

I thought I wouldn’t like working as a Product Owner and that I would be developing software for the construction industry

For several months I developed programming software for small and medium-sized construction companies. This project taught me a completely different approach to developing web applications. I had the opportunity to test the demo version and implement the first releases with the first customers. I also had an influence on the development of the application’s features based on feedback from the market.
