Hogen Adams


Overheard Conversations at a Busy Law Office

Although employees at Hogen Adams, a Minnesota law office specializing in Native American law, have a private office, conversations could often be heard through the office walls. This problem was particularly acute in the company conference room at the end of the hallway. As a result, some meetings had to be held offsite, which caused coordination nightmares and travel expenses. Vanya Hogen, a partner and co-founder at the firm, began looking for a solution. “We had this nice conference room that we couldn’t even use due to the confidentiality issues – one day I just decided that enough was enough,” Hogen says.

First insulation was added to the walls of the conference room, but speech sound continued to escape through the door and be overheard. Hogen began to search online for a technological solution to the problem. Searches for office white noise machines led her to sound masking solutions from Cambridge Sound Management.

More sophisticated than white noise, Cambridge Sound Management’s sound masking solutions emit a gentle, airflow-like sound into an environment through speakers installed in the ceiling. The noise is barely noticeable but is specifically engineered to cover up the sound of human speech, making it less intelligible and thus more private. Cambridge Sound Management worked with Hogen to schedule an onsite demo at Hogen Adams with a certified masking partner in their area. Impressed with the demo, the firm agreed to have sound masking installed in their office space.

“Since installing sound masking, meetings in our conference room can’t be overheard elsewhere in our office space, and neither can conversations in adjacent offices. I wish I had known about sound masking earlier!”
– Vanya S. Hogen, Partner, Hogen Adams


Qt® 100 Sound Masking System

Sound masking expert and independent AV contractor Gary Sundin installed QtPro™ sound masking from Cambridge Sound Management throughout Hogen Adam’s office space. Small, barely visible emitters (loudspeakers) were placed in the ceiling tiles throughout the space. The emitters were connected by cables to an intuitive wall mounted Qt® 100 control module. “Gary made the whole process easy, from demo to installation,” says Hogen.


A Pleasant, Comfortable, and Beautiful Work Environment

Employees don’t notice the masking sound, but they do notice that the law office is noticeably more acoustically comfortable, less distracting, and more private. “Since installing sound masking, meetings in our conference room can’t be overheard elsewhere in our office space, and neither can conversations in adjacent offices. I wish I had known about sound masking earlier!”
