IKS: Databases

Aachen Impulse Response Database

The Aachen Impulse Response (AIR) database is a set of impulse responses that were measured in a wide variety of rooms. The initial aim of the AIR database was to allow for realistic studies of signal processing algorithms in reverberant environments with a special focus on hearing aids applications.

Multi-Channel Impulse Response Database

Multichannel room impulse responses database. The impulse responses are measured in a room with configurable reverberation level resulting in three different acoustic scenarios with reverberation times RT60 equals to 160 ms, 360 ms and 610 ms.

Wind Noise Database

This database provides exemplary wind noise signals for the development and evaluation of noise reduction algorithms.

Paths for Active Noise Cancellation Development and Research

The IKS Paths for Active Noise Cancellation Development and Research (iks|PANDAR) is a set of impulse responses that were measured with the Bose QC20 In-Ear ANC Headphone without the manufacturers electronics. Covered are the primary, secondary and feedback path, which describe the transmission between inner and outer microphone as well as the transmission from the loudspeaker to the two microphones. The initial aim of the iks|PANDAR database is to allow for realistic studies of active noise cancellation algorithms.
