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.

Health Engineering Based on Vibroacoustics?

In the near future, technologies created by engineers will “repair” people from ailments, and the era of pills for everything will be reduced to a minimum. I am convinced that the time will come for many new technologies that will allow for home healing, cheaply and comfortably, and hospitals will only be needed for emergencies. I believe in an even greater development of vibroacoustics in medicine, diagnostics, physiotherapy, and inducing relaxation, which prevent the development of ailments and diseases.
