The East Central College board of trustees this week accepted a bid for the installation of an acoustic curtain in the college’s music department.

Sieve Contractors, Washington, provided the low bid of $28,400.

Bids also were received from Jasper Development and TJ Wies.

The bid includes installation of 18 sections of sound-absorbing fabric curtains 10 feet wide and 11 feet tall, that can be manually controlled.

The curtains will cover a concrete block wall and help dampen sound, said Phil Pena, vice president of finance and administration.

He noted that the college is working on a time line to install the curtain this spring. It will take four to six weeks to construct.

The curtain is one element of the sound mitigation project.

Sound panels have already been installed to help reflect the sound bouncing.

Installing acoustic doors also was recommended by a National Association of Schools of Music (NASM) sound engineer, said Dr. Jon Bauer, college president.

The doors likely will be installed this summer.

“We’ll get past the start of the fiscal year, so we’ll be able to submit for state reimbursement for half the cost,” he said. “It will also allow us to begin using the facilities fee, which we will start collecting with summer enrollment and then (again this) fall.”

The facilities fee was approved by the board of trustees this past fall.

A quote on the doors is about $50,000, Bauer said, however, the cost could be less if an equivalent rated door could be installed without adjusting door jams.

The curtain and doors are the two biggest expenses.

“It’s an expensive project, but one that we need to do both in terms of sound and its effect on an individual’s hearing and also the migration of sound through that area so it’s not distracting to other students,” Bauer said.

The sound engineer also recommended sound mitigation in the practice rooms and offices.

The college’s accreditation is pending, but the work is only part of the process and the college is hopeful to receive the NASM accreditation later this spring, said Joel Dopeker, vice president of external relations.
