A facilities team had purchased acoustic panels twice, and the occupant noise complaints continued. The panels were treating a symptom that measurement had never confirmed.

Memtech Acoustics measured the space with calibrated, NIST-traceable instrumentation. The measurement identified the cause as sound transmission between rooms rather than reverberation within a single room. Absorption does not address a transmission path, which is why the earlier panels made no difference.

Memtech corrected the transmission path and phased the work around an occupied, operating building, then measured again under the same conditions. The before-and-after data gave the facilities director documented results to present to leadership, and the recurring complaint was resolved.

Highlights

  • Two prior panel purchases had not resolved the recurring complaint
  • Calibrated measurement identified transmission between rooms as the cause, rather than reverberation within one
  • Corrective work was phased around an occupied, operating building
  • Before-and-after data gave the director documented results for leadership

Michigan Association of Conservation Districts

The Michigan Association of Conservation Districts measured reverberation as high as 4.0 seconds in the open meeting room at its Allegan office, a room used for board meetings and workshops. Memtech Acoustics measured the space and engineered a wall and ceiling panel layout modeled to bring reverberation under 1.0 second so staff can hear one another clearly.

Sylvan Lake Community Center

The Sylvan Lake Community Center's multipurpose room seats up to 150 for events, ceremonies, and film showings, but its vaulted ceiling and hard surfaces pushed reverberation to 1.9 seconds, well past the point where speech stays clear. Memtech Acoustics measured the room and engineered a ceiling and wall panel layout modeled to bring it to a 1.0 second target.

Apostolic Christian Church of Livonia

The dining hall at Apostolic Christian Church of Livonia grew hard to talk in when the room filled for gatherings of up to eighty people. Memtech Acoustics measured reverberation at 0.8 seconds, above the range a shared meal and conversation call for. Memtech engineered a wall panel and ceiling tile layout and confirmed by measurement that reverberation dropped to between 0.5 and 0.6 seconds.
