Effect on signal to noise ratio of clipping arctic accoustic data / by P. Zakarauskas, C.A. Hamm and J.M. Thorleifson.: DR52-11/12-1990E-PDF
"Arctic ambient noise is characterized by the presence of transients due to ice cracking. The present document reports the results of an investigation into the effect on signal to noise ratio (SNR) of clipping ambient noise time series to which artificial sinusoid signals had been added. Because the ambient noise contains more power at low frequencies than at high frequencies, it was deemed necessary to bandpass filter the time series before clipping. The effect of clipping on SNR was found to depend strongly on frequency. At low frequency the SNR was not greatly affected by clipping. At higher frequency, however, clipping was found to improve the SNR, by as much as 5 dB"--Abstract (page ii).
