Semi-Automated Analysis of Peak Amplitude and Latency for Auditory Brainstem Response Waveforms Using R

Many reports in the last 15 years have assessed changes auditory brainstem response (ABR) waveform after insults such as noise exposure. Common include reductions peak 1 amplitude and relative latencies of later peaks, well increased central gain, which is reflected by a increase amplitudes peaks compared to 1. experimenters identify troughs visually assess their heights latencies, laborious process when waveforms are collected 5 dB increments throughout hearing range for each frequency condition. This paper describes free routines that may be executed open-source platform R with RStudio interface semi-automate measurements waveforms. The troughs, display these on generated inspection, collate annotate results into spreadsheet statistical analysis, generate averaged figures. In cases automated misidentifies ABR waveform, there an additional tool assist correction. goal reduce time effort needed analyze so more researchers will analyses future.
