Samsung's audio lab

Founded in 2014, is the Samsung audio lab has been responsible for several new products from the company including the Samsung HW-K950 Atmos soundbar and the Radiant360 speaker . The facility is based in Valencia on the outskirts of Los Angeles, and now employs 20 scientists and engineers.

CNET visited the facility recently and found it includes some unique testing capabilities. Its founders say the lab will help the company become one of the biggest names in audio, in addition to its dominance of displays.

Inside Samsung's anechoic chamber

Samsung has not one but two separate anechoic chambers for testing audio components. An anechoic chamber is designed to prevent audio reflections and is used to test the frequency response of components; in this case, for freestanding and stand-mounted components.

What's it like being inside an anechoic chamber? It's a little weird because you can't hear your voice reflecting off walls. It's like having your ears filled with toilet paper.

The microphone

The calibrated microphone is mounted on an arm which can move up or down. The mount is covered in a fiberglass batt to absorb reflective interference.

Hemi-anechoic chamber

Samsung's second anechoic chamber isn't a walk-in like its partner, with only one chest-high door allowing access.

The hemi-anechoic chamber is designed to test wall-mounted products, including TVs and sound bars. It features a VESA mount on a hinged door and the movable microphone monitors how speakers interact with the wall behind it.

Computer mapping of frequency response

Using this speaker cone mapping system the Samsung engineers are able to monitor a speaker's frequency response in real-time.

Full-range tweeter

One of the drivers designed in the lab is Samsung's new "full-range tweeter." This is essentially a tweeter with holes in the side to port out low-frequencies. The engineers claim the response is more linear than other types of drivers, especially the kevlar drivers from Bowers and Wilkins.

Listening rooms

In addition to anechoic chambers, the facility is also used for subjective listening tests. The revolving wall pictured here is pretty unique. It allows the staff to mount four different TVs (or sound bars) on a revolving platform and toggle between them. In order to enable true "double-blind" listening, the wall is masked by an acoustically transparent screen.
