First Order Ambisonics field recordings for use in virtual acoustic environments in the context of audiology

These sound files were recorded using a Core Sound TetraMic microphone and an Edirol R4 portable recording device. The files were converted to B-format in FurseMalham normalization and channel order, using the software tetrafile from Fons Adriaenssen [3].

Files:

birds_oldenburg.wav:

Birds, recorded on an early Sunday morning in spring in a backyard in the city of Oldenburg, Germany. The recording is high-pass filtered to remove remote traffic noise.

mensa.wav:

Babble noise, recorded during lunch time in the cafeteria of the science campus of University of Oldenburg, Germany. The file was edited to remove intelligible conversations.

remote_traffic.wav:

Remote traffic sounds, recorded on a weekday in a backyard in the city of Oldenburg, Germany.

traffic.wav:

Dense traffic sounds, recorded close to traffic lights at a busy street crossing in Oldenburg, Germany.
