Swimming Pool Noise in Apartments – Diagnostics

The Challenge

“Planex Invest” Ltd. is an investment and consulting company specializing in the operation, management, and maintenance of urban, holiday, and commercial properties. This company contacted the team at Acoustic Forcerequesting that we carry out an investigation into a challenging and rather unusual complaint from one of their clients. The issue had arisen in the modern residential complex “Aquarelle” in Varna, which was designed and built by them. The complaint came from residents of an apartment located on the top floor of the building.

 

 

The residents complained of low-frequency noise coming from the swimming pool located on level minus two of the residential building.The task for our specialists was indeed intriguing and required a tailored approach, along with the development of a step-by-step plan to help reduce the unpleasant noises that were disturbing the residents’ peace.

Our Solution

The brief that reached the Acoustic Force team was unusual: the expected sound level in a swimming pool is not high, and the noise would also have to pass through six floors, so there was no obvious reason for such a complaint.

 

Here is how we approached it. We asked our client for the full design documentation so that we could examine every possible path of this unusual sound from the pool. Once we had it, we analysed everything in it in detail. The next step was a site visit. The Acoustic Force team measured the sound levels under real conditions. The measurements did not show any exceedance of the regulatory limits.

 

However, one subjective fact was noted: a sound within the range of human hearing was present. All the data we collected gave us a clearer picture of how to proceed. Based on this objective assessment, we prepared a project to locate and analyse the source of the sound and possible ways of reducing it.

The Execution

After a thorough analysis and examination of all possible options, we concluded that there were two potential causes of the noise:

– The first was the transmission of sound through sewage and ventilation pipes running from the swimming pool up to the top residential floor.

– The second possible cause was the installed stretch ceiling, which acts as a resonant “amplifier” of low frequencies, creating the so-called “drum” effect.

 

Based on the probable causes, we proposed specific soundproofing measures for the swimming pool to reduce the levels of unwanted noise. Our recommendations included:

– A step-by-step elimination of the causes, aimed at preventing the transmission of sound waves to the residential floor.

– Constructing soundproof enclosures around the pipes.

– Removing the stretch ceiling above the swimming pool.

 

In this way, our team once again provided valuable advice and outlined a concrete soundproofing plan, the implementation of which will undoubtedly contribute to the comfort of the apartment’s occupants, whose peace was being disturbed by low-frequency noise from the swimming pool. As experts with proven experience in the field of soundproofing, our primary goal is to deliver clear and precise solutions to any noise-related problems.
