Posted By Adam Jackson I'm looking to buy a new audiometer. I've got a few models in mind and am open to either a manual one or an all-singing all-dancing microprocessor one. Has anyone got any recommendations on good models or ones to avoid from their experience?

Posted By Calum R Cameron If you are going to buy one for doing noise surveys in relation to action levels and hearing protection you would be wasting your money if you don't buy one that does octave band analysis. Hearing protection attenuates sound differently at different frequencies. Make sure you are suitably trained to carry out the survey. All the best.

Posted By Adam Jackson Its not for noise surveys, its for measuring individual's hearing ability and determining if they are likely to be showing a hearing loss which potentially may be as a result of noise exposure. I've used both a manual one in the past, which was OK, and a whiz-bang laptop-controlled one for doing tests in America. I've been using the American one for a while here but its time for a new one. Sadly the one I'm used to using isn't available here. The manual ones are good in that you have complete control over the test and work wth the subject. The elecy ones have extra features which save a lot of time and improve results such as before and after automatic calibration checks, monitoring of background noise levels and automatic suspension of the hearing test if they get too high, etc.
