Peter Kember (born 19 November 1965) is a British musician, more usually known as Sonic Boom.

Kember and Jason Pierce (born on the same day in Rugby, Warwickshire) formed Spacemen 3 in 1985. Sonic Boom's first solo album, Spectrum, was recorded in 1989 while Spacemen 3 were still a going concern, and featured the other members of the group. However, by 1991 relations with Pierce had broken down, and while Pierce went on with the other members of Spacemen 3 to form Spiritualized, Kember recruited new musicians for the group Spectrum. He has also recorded as E.A.R. (Experimental Audio Research) - the two projects have existed in parallel, and recordings under both names occasionally only feature Kember.
