02 Dec NS-100 Transmission Loss Tester
To test transmission loss, Marcel Rivard and Gordon Hall design the NS1, a portable speaker/pink noise generator capable of testing STC 60 with reliable results. Later the NS1 becomes the NS-100, a Tracoustics product that is licensed by Barron & Associates and used for decades. The plaid slacks are an optional accessory.
