Course introduction
The inner hair cells (IHCs) are the transducers of the cochlea; they convert mechanical vibrations to neural activity. When the IHCs, neurons, or synapses between IHCs and neurons are non-functioning over a certain region of the cochlea, this is referred to as a dead region. A Dead region can be defined in terms of the characteristic frequencies of the IHCs immediately adjacent to the dead region. Dead regions can be detected, and their limits can be determined, by measurement of psychophysical tuning curves (PTCs), including “fast” PTCs or using the “TEN” test; the latter involves the measurement of detection thresholds for pure tones in threshold-equalizing noise (TEN). Both fast PTCs and the TEN test can be used to assess children as young as 7 years of age. The diagnosis of dead regions can be important for predicting the likely benefit of hearing aids, the fitting of hearing aids to both adults and children, selection of signal processing in hearing aids (e.g. the use of frequency compression or transposition), and assessment of the suitability of a patient for a cochlear implant or combined acoustic-electric stimulation.
Learning Objectives:
At the conclusion of this seminar the participants will be able to:
• Describe the Dead Region
• Discuss how to diagnose a Dead Region and define its extent
• Describe the extent of a Dead Region in relation to to the Fitting of Hearing Aids
• Discuss the extent of a Dead Region to the selection of signal processing in hearing aids

Brian Moore is Emeritus Professor of Auditory Perception in the University of Cambridge. His research interests are: the perception of sound; development of new diagnostic tests of hearing; design of signal processing hearing aids for sensorineural hearing loss; methods for fitting hearing aids to the individual. He is a Fellow of the Royal Society, the Academy of Medical Sciences, the Acoustical Society of America, The Audio Engineering Society, The British Society of Audiology, and the Association for Psychological Science, and an Honorary Fellow of the Belgian Society of Audiology and the British Society of Hearing Aid Audiologists. He is President of the Association of Independent Hearing Healthcare Professionals (UK). He has written or edited 20 books and over 730 scientific papers and book chapters. He has been awarded the Littler Prize and the Littler Lecture of the British Society of Audiology, the Silver and Gold medals of the Acoustical Society of America, the first International Award in Hearing from the American Academy of Audiology, the Award of Merit from the Association for Research in Otolaryngology, the Hugh Knowles Prize for Distinguished Achievement, and an honorary doctorate from Adam Mickiewicz University, Poland. He is wine steward of Wolfson College, Cambridge. In his spare time he likes playing the guitar and fixing things.
