Resonance at the front of lightning impulse voltage waveforms caused by the load capacitor
<p>Numerical simulations with NI-Multisim had been done to verify the hypothesis. Fig. 5 illustrated the simulated waveform , when was set to 150‍ W and was set to 350‍ W. Fig.‍ 5(a) shows the simulated result when no inductance was considered. But for actual circuit, inductance is not negligible. When inductances were added to the circuit in series with the capacitance and resistance, the voltage step would be less steep, and oscillation would appear at the front period. Fig.‍ 5(b) shows the simulated waveform when 0.5‍ mH, 1‍ mH and 2‍ mH inductances are in series with sphere gap (FS), and respectively. These values were estimated according to the LI waveform generation circuit used in my test, and with an approximation that the lead inductance is around 1‍ mH/m.</p>

BRUDEX Database: Binaural Room Impulse Responses with Uniformly Distributed External Microphones
<p>There is an emerging need for comparable data for multi-microphone processing, particularly in acoustic sensor networks. However, commonly available databases are often limited in the spatial diversity of the microphones or only allow for particular signal processing tasks. In this paper, we present a database of acoustic impulse responses and recordings for a binaural hearing aid setup, 36 spatially distributed microphones spanning a uniform grid of (5x5) m^2 and 12 source positions. This database can be used for a variety of signal processing tasks, such as (multi-microphone) noise reduction, source localization, and dereverberation, as the measurements were performed using the same setup for three different reverberation conditions (T_60≈{310, 510, 1300} ms). The usability of the database is demonstrated for a noise reduction task using a minimum variance distortionless response beamformer based on relative transfer functions, exploiting the availability of spatially distributed microphones.</p> <p><br>An example how to load a impulse responses corresponding to the 'low' reverberation condition for the speaker located at 60 deg using MATLAB:<br> dataStruct = loadRIR('low',60,1,<basePATH>);%<basePATH>: path where database is located on local machine<br>For further MATLAB examples, please consider "wrapper_loadDataFromDB.m" in the "matlabScripts.zip" archive file.</p> <p>An example how to load a impulse responses corresponding to the 'low' reverberation condition for the speaker located at 60 deg using Python:<br> dataloader = wrapper.BRUDEXDataloader()# <basePATH> is implicitly set to that path, where the file "wrapper.py" is located on local machine<br> dataStruct = dataloader.load_rir(reverberation_condition='low', direction_of_arrival = 60, ha_av = 1,e_mic_run = None)<br>For further Python examples, please consider "main.py" in the "pythonScripts.zip" archive file.</p> <p>Caution: We noticed some problems with the download of the databse when using the command line (e.g., via the zenodo_get, wget, or curl commands).

That is why the noise is approximately spatially diffuse only in the vicinity of the center of the room and rather spatially coherent in the corners of the room.</p> <p>Caution 4: Oppposed to Zenodos information, the database does not contain 3 TB of data but about 200 GB.</p> <p> </p> <p>Reference:</p> <p>D.

Binaural room impulse responses for interactive listener translation in a seminar room
<p>With the goal to study the perception of position dynamic binaural synthesis for walking listeners wearing headphones, a set of binaural room impulse responses (BRIRs) and omnidirectional RIRs was measured. The measurements were conducted with a Kemar 45BA dummy head in a seminar room (9.9m x 4.7m x 3.1, T60 = 1.0s). Two loudspeakers Genelec 1030A served as sound sources. The BRIRs were measured at 16 positions arranged along a line towards the frontal loudspeaker with distances ranging from 1m - 8.50m and a positional resolution of 50cm. The second source was placed at the side of the line. The BRIR were determined for a full 360° rotation in 4° steps for each of the measurement positions. In addition, omnidirectional RIRs were measured at the 16 listening positions.</p> <p>As a second test case, on a different day both loudspeakers were turned by 180° to be pointing away from the translation line. BRIRs were captured for the positions with the same angular resolution. The interior slightly differed from the first measurement. The changes are documented with photos of the room and the measurement setup.</p>
