What is the difference between DD45, DD65 and DD450 headphones?
The DD45 is a supra-aural headphone designed to rest on the ear and does not completely fit over the ear. This headphone allows providers to obtain hearing test results at 250 Hz through 8000 Hz.
Both the DD65 and DD450 are circumaural headphones designed to completely encase or surround the ear, sealing the ear off from the environment. The circumaural design provides additional attenuation to significantly improve outcome and accuracy of hearing tests, making the DD65 and DD450 ideal for boothless audiometry (i.e., testing hearing outside of an audiometric booth).
While the DD65 and DD450 may be used for boothless audiology and look very similar, they are different. The DD65 headphone is a DD45 headphone inserted a DD450 encasement; like the DD45, the DD65 allows providers to obtain hearing test results at 250 Hz through 8000 Hz. In contrast, the DD450 headphone allows providers to obtain hearing test results at 250 Hz through 16000 Hz. The DD450 headphone (or comparable headphone) is specifically designed to extended frequency audiometry.
