Abstract

Good hearing is extremely important, and considerably affects our daily activities and life. Hearing loss, deafness and general problems with hearing is something we increasingly encounter. Thanks to the rapid and constant advancement of technology there are a number of subjective and objective methods of examining hearing, which enables diagnosing the damage and organisation of necessary rehabilitation. One such method is the speech audiometry. Speech audiometry is testing the intelligibility of words with respoct to the threshold of hearing and the threshold of intolerance to sound. Principles of speech audiometry of Croatian language were set by Peter Guberina. Speech audiometry lists have been completed in 1953 and the following principles were applied while preparing them: frequency of monosyllabic and bysillabic words in the language, word stress, phonetic balance and sound and word levels. The results of speech audiometry are presented as curves of the speech audiogram the shape of which will depend on the type and degree of damage. Speech audiometry today has great importance and wide application in the diagnosis of hearing impaired persons. Apart from the standard speech audiometry there is also noise sensibilized speech audiometry, slow speech audiometry and filtered speech audiometry. Due to the noise which makes it more difficult for a patient to hear, noise sensibilized speech audiometry will show patient's temporal integration and selective hearing. It also helps at detecting presbycusis. Slow speech audiometry, as its name would suggest, is using slowly pronounced words with longer pauses between them to test intelligibility of words. This type of speech audiometry is not very significant in diagnosis of hearing. Filtered speech audiometry covers the entire area of hearing and is the only type of audiometry that can test intelligibility measuring at the same time frequency and intensity segments. It is rarely used in practice, but it's very useful in diagnosing hearing loss, deciding on rehabilitation and choosing the right hearing aid.
