Dataset related to An objective comparison of quality and reliability of auditory brainstem response features elicited by click and speech sounds

The data was recorded in the programme 'Signal' version 4 made by Cambridge Electronic Design: ced.co.uk.There are 16 subjects. For subjects 1-9 and 15, the files are in CED format (.cfs), so these would need to be opened in 'Signal'. For subjects 10-14 and 16 the data have been exported as .txt files so that they can be loaded into Matlab directly.The first row is time and the second row is voltage. Note that an amplified with gain 10,000 was used, so to convert to voltage at the scalp, divide all values by 10,000.
P is for participant, ck indicates click stimulation, Da indicated Da stimulation, 1 and 2 indicate repeats, N65 indicates a recording in background noise and NN indicates no stimulation level. e.g.for Participant 12 there are 7 files...
P12ck1.txt - 1st click recording in quiet
P12ck2.txt - repeat click in quiet
P13ckN65.txt - click in 65 dB noise
P12Da1.txt - 1st Da in quiet
P12Da2.txt - 2nd Da in quiet
P12CkN65.txt - Da in 65 dB noise
P12NN.txt - no stimulation dataAn example matlab analysis file 'Time_and_Freq_analysis_ABR_speech.m' is included. This shows how to load in data, how it was filtered, averaged, artefact rejected and then time and spectral bootstrapping is carried out.The file 'Data_Description_Readme.txt' gives more detail of the recording of the data. It can also be found in the paper associated with this dataset (see dataset title). Participant 16 had particularly good data quality as an exemplar.Approval for the study was given by The University of Southampton Ethics Committee (ERGO Ethics Number: 2411)
