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.

Intuitive creative process vs algorithms

🥱 Bored with “Lean” and “Six Sigma” – methods common in Automotive, I was looking for knowledge on how to approach problem solving innovatively. Methodological optimization and “nibbling” percentages is not always the right solution, when it’s begging to be “turned upside down”. My creative approach in problem solving was ‘somehow’ intuitive, based on ‘some’ experience, being ‘somehow’ more open to solutions and ‘somehow’ having flashes of ideas. Often this approach led me to come up with ‘some’ solution. However, I was also often left with an idea and the thought “what next?”.
