No I've got four and about to have six in my office. The Spectralis has a sound like that of a hearing aid whining but causes no hearing problems. Its just annoying at first then after a while you seem not to notice it any more. The HRA was much loader and gave off a lot of heat. Thing of the Spectralis as the Ferrari of cameras it has a strange sound but runs and does like no other camera can. If you need any help you can call me.
