This paper describes the relationship between the scores obtained in the Bamford, Kowal and Bench (BKB) sentence test and the Arthur Boothroyd (AB) word test in quiet for a group of 71 cochlear implant users. Each subject was tested at the same appointment and in the same environment during routine clinical appointments at the South of England Cochlear Implant Centre.Using rationalised arcsine transformation and a linear regression calculation, conversion tables were produced from BKB to AB and from AB to BKB scores. The relationship between scores obtained from the two tests was highly significant.These conversion tables may be of use in cochlear implant centres and by audiology clinics.
