Most of the following facilities are used for teaching and research by both Acoustic Technology and the Centre for Applied Hearing Research.
 |
64-channel EEG recording system and a soundproof and electronically shielded listening booth. This system is used for objective measures such as auditory evoked potentials. |
 |
A virtual auditory environment consisting of 29 loudspeakers. This system was developed in our lab and is also referred to as SpaceLab. It is fully controllable and is used for sound reproduction in simulated rooms. Aspects of spatial hearing can be systematically investigated and the setup allows for listeners to wear hearing aids during the test.

|
|
An otoacoustic emission (OAE) recording system. This system is flexible and allows us to investigate OAE recording techniques with advanced stimuli.
|
 |
Two anechoic rooms; a large and a small one. These rooms are, e.g., used for recording of speech and music stimuli which are later used in psychoacoustic tests.
|
 |
An audiological clinic with equipment for audiometry, middle ear analysis, otoscopic inspection, and hearing aid measurements. |
|
|
A listening room according to IEC 268-13 for e.g. loudspeaker comparison. |
|
|
One bigger acoustically and electrically shielded listening booth used for measurement of electroencephalography (EEG) and otoacoustic emissions.
|
|
|
Acoustically and electrically shielded listening booths used for audiometry, psychoacoustic and speech intelligibility experiments where sound is typically presented over headphones.
A master hearing-aid platform. This is a fully flexible system by which we can systematically test effects of state-of-the-art hearing-aid signal processing, as well as develop innovative compensation strategies.
