"In some criminal trials judges do not agree with requests from the defence lawyers that ear-witness evidence may be so error prone that such evidence should not be allowed to form part of the prosecution case. Instead, they sometimes allow an Expert Witness (such as myself) to testify (e.g. inform the jury) (i) about research findings on the general reliability of ear-witnessing (such as that mentioned above) and (ii) on factors directly relevant to the ear-witness evidence being presented in that particular trial. Regarding the latter I have, for example, conducted experiments for and testified in a number of trials."

TWO EARS NOT NEEDED TO HEAR DISTANCE
"The main result of the study is that listeners did not need two ears to evaluate the sound source distance in our experiments: binaural and diotic signals led to the same perceived distance for stationary signals such as noise. Distance perception was not disrupted for sounds identical at the two ears; it was monaural and based on room colouration."

ACOUSTIC OBSERVATIONS OF DEEPWATER HORIZON OIL SPILL
"By mid-May, observations of underwater oil plumes were reported, and later that month we embarked on the first of many cruises onboard NOAA research ships with the principal aim to use scientific echo sounders (i.e. sonars) to map subsurface gas and oil near the wellhead. Over the next few months, we used these echo sounders to map the many natural methane gas seeps in the area, to directly observe the oil in the top few hundred meters of the water column, to examine some of the local effects of the oil plume on marine organisms throughout the water co
