Acoustiblok’s All Weather Sound Panels have a reputation in the industry as an effective solution for difficult pump and generator noise issues because of their unique properties. They are not only sound blocking, but sound absorbing. This means they absorb reflective noises and also stop sound from penetrating through the panels. The panels have an extraordinarily high STC of 29 (Sound Transmission Class), as the panels contain large amounts of Acoustiblok’s award winning viscoelastic polymer material. This vastly superior innovation uses the isothermal adiabatic principle; as sound waves cause the Acoustiblok material to flex, internal friction occurs and the acoustical energy is dissipated into a very small trace amount of heat.
In addition to being very effective on high frequency noise, AWSP’s are also effective on low frequencies; the most difficult sound blocking problems are the low frequencies (30 to 100 HZ). The annoying bass in music is predominately 40 to 80 HZ. Conventional sound barriers do dramatically less sound blocking below 100 HZ, however, because of the Acoustiblok barrier material built into each of the All Weather Sound Panels they actually increase in sound blocking from 100 HZ down.
Engineered specifically to withstand the most rigorous outdoor and industrial environments; water, moisture, humidity, salt air/water, dirt, dust, constant ultraviolet light, chlorine air, grease, or corrosion; even the harshest chemicals are not a problem for AWSP’s. Because they are encased by all-welded aluminum they also prohibit vermin problems.
“In this case, in addition to the noise reduction goals for the project, the environment was a key consideration in selecting the right sound barrier solution for the project. The heat, cold, rain, fluctuating temperatures, constant UV exposure and the intense Santa Ana Winds that can generate wind speeds up to 70-80 miles per hour at times made Acoustiblok’s All Weather Sound Panels the ideal choice. They do a superior job of mitigating the noise and are also rugged enough to withstand that environment for years to come,” said Lahnie Johnson, president and founder of Acoustiblok Corporation.
A sound meter was used to measure the noise levels inside the enclosure and outside once the panels were placed in position. The sound meter readings inside the enclosure close to the pump were 89dB. The reading outside the enclosure (behind the All Weather Sound Panels) was 65dB (see photos). This indicates a noise reduction of 24 decibels. In a 10 decibel decrease in sound level, perceived loudness is cut in half to the human ear.
“The installation went smoothly and didn’t take much time at all. We didn’t encounter any unexpected problems and were very pleased with the reduction in sound decibels picked up by the meter,” said Ben.
With the noisy pump problem resolved, Ben concluded, “Acoustiblok’s All Weather Sound Panels were an excellent sound solution for us; the cost was reasonable and I wouldn’t hesitate to recommend them for a similar job application like this one.”
