Selection of an Acoustical Consultant
November 20, 2019
Noise Monitoring Services was recently approached by acoustical products company Echo Noise Control to provide noise modeling for their ENC STC-26 construction noise blankets. These composite sound barriers are designed to reduce noise from construction sites as well as many other outdoor situations. Our work involved calculating and mapping the noise reduction produced by the blankets for various scenarios.
The Echo Noise Control STC-26 temporary construction noise barriers are constructed from an exterior-grade, UV resistant and fire resistant materials. The barriers have been acoustically tested and provide a Sound Transmission Class (STC) rating of 26 and a Noise Reduction Coefficient (NRC) of 0.70. Our noise mapping work (see example below right) shows a large reduction in sound levels is possible.

Unmitigated Results
Using the environmental noise monitoring software Soundplan, we have the unmitigated scenario with no temporary construction noise barriers. The noise propagation shown here is the construction site as it would affect the neighboring areas prior to the installation of Echo Noise Control's STC-26 temporary acoustic blankets.

Six Foot ENC STC-26 Sound Wall Performance
Using the environmental noise monitoring software Soundplan, we have modeled our STC-26 barrier in order to simulate the noise reduction effectiveness of the ENC STC-26 six foot sound wall on a construction site. The noise contour map shows the difference between the unmitigated east and mitigated west noise levels as they propagate across the affected area.

Twelve Foot ENC STC-26 Sound Wall Performance
Using the environmental noise monitoring software Soundplan, we have modeled our STC-26 barrier in order to simulate the noise reduction effectiveness of the ENC STC-26 twelve foot sound wall on a construction site. The twelve foot wall shows an increase in noise mitigation showing that an increase in wall height can be utilized to further reduce unwanted construction noise when necessary.
