A hardware and software approach is presented in this paper to measure the room impulse response that defines the transmission of audio signals in a room. This approach was developed within the European SpeeCon project [1]. Graphical user interfaces have been designed to estimate the room impulse response from the recordings of noise signals that are transmitted in the room and to analyse the i...

The double impulse is introduced as a substitute of the fling-step near-fault ground motion and a critical elastic–plastic response of a two-degree-of-freedom (2DOF) building structure under the “critical double impulse” is evaluated. Since only the free-vibration appears under such double impulse, the energy balance approach plays an important and essential role in the derivation of the soluti...

The study of impulse response technology allows audio engineers to attempt to recreate the tonal characteristics of a certain device. The purpose of this project was to recreate a sonic representation of analog microphone pre amplifiers and acoustic spaces through the use of impulse response technology. By creating these impulses, the student will attain the sonic characteristics of professiona...

We propose a blind dereverberation method based on spectral subtraction using a multi-channel least mean squares (MCLMS) algorithm for distant-talking speech recognition. In a distant-talking environment, the channel impulse response is longer than the short-term spectral analysis window. By treating the late reverberation as additive noise, a noise reduction technique based on spectral subtrac...
