Condominium Complex Soundproofing

Soundproof Windows work well in residential soundproofing, and commercial building soundproofing. Find out how soundproofing helped reduce traffic noise in this downtown Los Angeles complex.

A multi-million dollar project taking 3 years to complete, the Mozaic Apartments, developed by Lincoln Properties, were justified in describing their intentions as follows:

It’s our goal to bring a designer lifestyle to downtown Los Angeles apartment living. From our roof top pool to our Internet café, Mozaic apartments set the standard in a luxury apartment community.

And they go on to say:

Mozaic features a variety of studio, one, and two bedroom floor plans. Each apartment includes washer and dryers, granite countertops, premium appliances, and many units enjoy floor to ceiling windows and private balconies.

Soundproofing Required

Of course, being in the middle of downtown also involves one other factor not mentioned above: an incredible amount of street noise. Even given the high end amenities, the amount of outside noise could be prohibitive and turn off potential tenants without adding soundproofing. With lease rates in the downtown area commanding upwards of $3000 per month, not having a 100% occupancy rate could be expensive. Lincoln Properties decided the best soundproofing tactic would be to exceed the government noise abatement requirements to help attract prospective residents.

The Soundproofing Solution

“We wanted to provide a high quality of life to our tenants and we felt that included a quiet environment,” said the project manager for Lincoln Properties, Sasha Cooper. “To exceed the Los Angeles requirements by soundproofing and be noticeably quieter than our competition, we set some tough noise reduction targets.” He invested his time in research and discovered our soundproofing solution on the internet.

They hired an acoustic consulting firm, Veneklasen Associates, to do a detailed site survey and review as well as extensive sound testing to evaluate the noise levels.

Initially, high quality double pane windows were installed and tested, but these turned out to fall short of their target. The next step was to install Soundproof Windows in several of the nosiest units and perform more sound tests to evaluate the soundproofing results.

The soundproofing surpassed their expectations and noise reduction goals in every room tested, and even amazed John LoVerde, the associate principal consultant from Veneklasen. “I had heard of Soundproof Windows previously and was impressed after testing their installed product.”

“The windows exceeded our requirements for soundproofing. Now, despite all the downtown city noises outside, all our units have a very quiet and less stressful living environment,” explained Cooper.

A Wall of Noise

Particularly challenging were the units requiring soundproofing which had floor to ceiling windows. “We didn’t expect to see as much difference in the level of noise because of the number and size of the windows,” Cooper said, “But we were quite surprised and pleased with the results.”

All units facing the busy streets had soundproofing installed.


These Soundproofing Windows are Practically Invisible

Another great aspect of these soundproofing windows is how well they fit in with the décor. Looking at this room, you wouldn’t know that a powerful STC 55 rated Soundproof Window has been installed.
