Noise pollution from heat pumps? Discover green solutions

More and more homes are being equipped with a heat pump – a sustainable, efficient and future-proof heating solution. But there’s a downside: noise pollution. Many users and neighbors experience noise nuisance from their heat pump, particularly due to the constant humming and buzzing of the outdoor unit. Fortunately, there are effective solutions available. Mobilane offers two soundproofing systems – NoiStop and NoiStop Green – that significantly reduce heat pump noise pollution, without compromising on appearance or sustainability.

Why does a heat pump make noise?

A heat pump operates using a fan and compressor. It’s primarily the outdoor unit that produces noise levels of up to 50–65 decibels, depending on the brand and installation. That’s comparable to the noise level in a busy office or a conversation at normal volume. When this sound is constantly audible in the yard, on the patio or even indoors, it can become a serious nuisance.

The impact of heat pump noise on quality of life

Prolonged exposure to low-frequency noise – such as that from heat pumps – can cause stress, concentration problems and reduced sleep quality. For nearby residents, it may lead to complaints or even legal action if noise limits are exceeded. That’s why it’s important to tackle heat pump noise pollution at the source.

Noistop: sound reduction with a clean finish

NoiStop is a ready-made acoustic screen solution that reduces heat pump noise by up to 25 dB(A). Its sound-absorbing core, made of special stone wool, absorbs ambient noise instead of reflecting it. Ideal for installation between the heat pump and property boundary or against a wall.

Key benefits of Noistop:

• • Up to 25 dB(A) sound reduction

  • Direct, measurable improvement to the sound environment

  • Low-maintenance and weather-resistant

  • Modular: easy to customize and install

Noistop Green: sound reduction and greenery combined

Those who value a natural look alongside effective sound reduction will appreciate NoiStop Green. This system combines the same sound-absorbing performance with a climbable mesh panel designed for planting. The result is a green noise barrier that not only reduces noise, but also promotes biodiversity, cooling, and CO₂ absorption.

Additional benefits of Noistop Green:

• • Same acoustic performance as Noistop

  • Green, natural appearance

  • Part of climate-adaptive landscaping solutions

  • Suitable for walls, yards, and property boundaries

The ideal solution for heat pump noise pollution

Whether you prefer the sleek finish of Noistop or the natural look of Noistop Green, both systems offer a sustainable, effective and visually appealing solution to heat pump noise problems. They meet current noise regulations and contribute to a more comfortable living environment – for both you and your neighbors.
