I would think that humans hear high pitches better. As humans age, our hearing diminishes, usually affecting the higher frequencies (pitches) first. The hearing range of a young person is about 20Hz to 20KHz an the response is reasonably flat. Due to ageing factors, eardrum thickening, small hairs flattening, work noise etc., a middle aged man might have a response of 14Hz to 14KHz with 'notches' of attenuation relating to the frequency of ambient work noise. Womens hearing degrades at a slower rate than men. See also: http://www.dspguide.com/ch22/1.htm

It typically consists of padded cups that cover the ears and are connected by a headband, providing a snug fit to block out loud sounds. Ear defenders are commonly used in noisy environments, such as construction sites, shooting ranges, and during industrial work, to help prevent hearing damage and promote auditory safety.
