Soundproofing an Indoor Pool

Indoor pools, also called natatoriums, are notorious for poor acoustics. Hard surfaces like concrete ceilings and walls reflect sound, causing excessive echo and reverb. This makes it difficult for lifeguards, instructors, and swimmers to communicate effectively—a potential safety issue.

Adding to the noise, mechanical equipment like pool pumps and filtration systems hum and vibrate, creating a constant background noise that amplifies in the enclosed environment. Addressing both these issues is essential to create a safe and enjoyable space for all users.

Pool pumps are critical for maintaining clean and healthy water, but they can also be one of the loudest components in an indoor pool. Vibrations, mechanical humming, and water flow noises from pumps and filtration systems can reverberate throughout the space. Without proper soundproofing, these sounds disrupt the atmosphere and create unnecessary stress for patrons and staff.

Here are practical solutions for reducing pool pump noise:

Enclosing the pool pump in a soundproof enclosure is one of the most effective ways to block noise. A custom-built or pre-fabricated pool pump quiet box lined with acoustic materials can absorb sound and reduce vibrations.

For smaller spaces or outdoor pools, a soundproof cover can provide an alternative solution. Look for covers designed with acoustic foam or vinyl barriers to dampen sound while maintaining airflow for the pump’s cooling needs.

If the pump is located in a mechanical room, soundproofing the wall can isolate noise effectively. This can be achieved using AudioSeal® Mass Loaded Vinyl (MLV) Soundproofing Barrier or a PrivacyShield® Industrial Sound Enclosure if the size and space around the pump allow. Then the door may be sealed with an Acoustic Door Seal Kit.

Vibrations from pool pumps can transfer through the floor and amplify in the pool space. Installing anti-vibration pads beneath the pump minimizes this structural noise. These pads are especially effective on concrete floors.

Once the pump noise is managed, improving the pool’s acoustics is the next step. Here’s how to address echo and reverb in the natatorium:

Suspending sound-absorbing materials from the ceiling is one of the most effective ways to manage acoustics in a large open space. Products like the AlphaSorb® PVC Plastic Acoustic Sound Baffles and AlphaFlex® PVC Ceiling Banners reduce echo and improve speech intelligibility without interfering with activities below.

If wall space is available, consider installing AlphaSorb® PVC Plastic Acoustic Panels. These panels are moisture-resistant, easy to clean, and highly effective at reducing reverb.

For a more aesthetic option, AlphaSorb® Flat Acoustic Foam can be installed on walls or ceilings. These panels come in various designs and colors, adding a decorative touch while improving sound quality.

It’s important to recognize the difference between managing echo and reverb in the pool area and addressing mechanical noise from pool pumps. While ceiling and wall treatments absorb sound to improve communication and comfort, soundproofing the pump requires blocking and isolating noise at the source. Together, these solutions create a balanced acoustic environment.

For a safe and enjoyable pool environment, aim for these reverberation times:

Combining sound-absorbing materials with effective pump soundproofing ensures you meet these targets.

Soundproofing an indoor pool requires addressing both the acoustics of the space and the mechanical noise from pool pumps. At Acoustical Solutions, we offer industry-leading products to tackle these challenges, from ceiling baffles and acoustic panels to soundproofing blankets and barriers for pool equipment.
