Mathematical Statistics
Abstract (Swedish)
The time-frequency (TF) spectral representation of Auditory Brainstem Response (ABR) signal data
provides information about their spectral contents. We apply the Spectrogram, Thomson Multitaper and
Peak Matched Multiple Window (PM MW) spectral estimation methods to four different number of clicks
per average (i.e., 1313, 300, 100 and 50 number of clicks per average) of a simulated signal data. For the
purpose of model selection we simulate sinusoidal signal data which have the same trend as the empirical
ABR signal data, and then apply the selected model to ABR data from 17 healthy, normal hearing individual
ears as recorded using SD-BERA, SensoDetect-Brainstem Evoked Response Audiometry. The root mean
square error (RMSE) is the... (More)

Spectrogram is found to be an appropriate method of spectral estimation for signals with relatively low
disturbance. In particular, for signals with a white disturbance with standard deviation, , value in the
interval 0,15.0, it is found to be best of the three methods. For 15.0 ≤ ≤ 30.0, the PM MW method
performs as good as the spectrogram, if not better. Finally, for ≥ 30.0 the PM MW continues to be the
best of the three methods where as the Spectrogram turns out to be worst of them. (Less)
