In this article, we’re going to take a closer look at the science of hearing, how the human ear works, the concept of hearing range, and the role of frequency in our auditory experiences. How Does the Human Ear Work? The human ear is a complex and remarkable organ that’s responsible...
Frequency selectivity is a key functional property of the inner ear and since hearing research began, the frequency resolution of the human ear has been a central question. In contrast to animal studies, which permit invasive recording of neural activity, human studies must rely on indirect ...
The frequency-following response (FFR) provides a measure of phase-locked auditory encoding in humans and has been used to study subcortical processing in the auditory system. While effects of experience on the FFR have been reported, few studies have examined whether individual differences in early...

The human auditory cortex is recently found to contribute to the frequency following response (FFR) and the cortical component has been shown to be more relevant to speech perception. However, it is not clear how cortical FFR may contribute to the processing of speech fundamental frequency (F0)...
The term “octave band” is borrowed from music theory (Figure 2) where there is a doubling of frequency between notes of the same name. Figure 2: In music, there is a doubling of frequency between notes of the same name. Octave bands in human hearing are developed in the same manner:...
Indeed, from birth, the cochlea is the organ that makes a more crucial contribution than the middle ear in setting the hearing range13. The cochlea also imprints details of its overall adult-like structure within the petrosal, the hardest and most dense bone in the mammal body that is most...
As a result, the ear tends to have hearing ‘bands’. These bands increase in bandwidth from low to high frequency as shown in Figure 1.Figure 1: Bandwidth of critical band increases with frequencyThe bands are defined in a similar manner to bandpass filters, with a center frequency, and ...
The ear-canal impedance and reflection coefficient were measured in an adult group and in groups of infants of age 1, 3, 6, 12, and 24 months over frequency range 125-10,700 Hz. The development of the external ear canal and middle ear strongly affect input impedance and reflection coeffici...
Design of differential electromagnetic transducer for implantable middle ear hearing device using finite element method This paper describes the design and implementation of a differential electromagnetic transducer (DET), with similar frequency characteristics to those of a...
