What is Quiet Mark?

Quiet mark is an independent, global certification which uses scientific testing and assessment to identify the quietest products on the market. This spans many sectors, including home appliances, building sector materials, and commercial sector products.

Reducing noise helps to improve health and wellbeing, which is why Quiet Mark provide reliable consumer and trade information before purchase.

Noise and our health

Yes! It’s true. Excessive noise can have a damaging effect on health, productivity, and social cohesion. Research done by the World Health Organisation shows that environmental noise pollution is second only to air pollution as the world’s largest killer pollutant. Fast paced, modern lives can only be sustained in the long term if there is an opportunity to seek a calm, quiet alternative. Noise pollution prevents this. Noise annoyance has also been linked to anxiety, depression, hypertension, increased secretion of stress hormones, thickening of the blood, and cardiovascular disease.

The Quiet Mark certification helps consumers to refine their environment, avoiding loud, irritating sounds in favour of quieter options.

How Quiet Mark certifies products

Quiet Mark determines what products are suitable for certification by assessing the declared technical data and conducting acoustic measurements in purpose-built laboratories with specialist lab partners.

This acoustic data is then compared like for like with products in each category and the quietest 10 – 20% are awarded Quiet Mark Certification.

Each product’s category is re-evaluated annually to ensure the data is up to date and incudes new products entering the market.

Why Quiet Mark don’t use decibels

Sound measurement is complex. Sound levels are commonly measured in decibels, but this can be more difficult to interpret than you might think. Surely something that is 63dB is 3 ‘levels’ more noisy than something that is 60dB? Well, no. A 3 decibel increase actually means the sound intensity has doubled. So a 63dB appliance is twice as loud as a 60dB appliance.

Similarly, sound context needs to be taken into account. The same sound can be perceived differently in different places, at different times, and depending on how you feel about it. A sound doesn’t have to be loud to be annoying.
