Frequency response. In signal processing and electronics, the frequency response of a system is the quantitative measure of the magnitude and phase of the output as a function of input frequency. [1] The frequency response is widely used in the design and analysis of systems, such as audio and control systems, where they simplify mathematical ...
Generally speaking, the HRTF boosts frequencies from 2–5 kHz with a primary resonance of +17 dB at 2,700 Hz. But the response curve is more complex than a single bump, affects a broad frequency spectrum, and varies significantly from person to person.
Good headphones, well sealed to the ear, provide a flat low-frequency pressure response to the ear canal, with low distortion even at high intensities. At low frequencies, the ear is purely pressure-sensitive, and the cavity formed between headphones and ear is too small to introduce modifying resonances.
High-quality headphones can have an extremely flat low-frequency response down to 20 Hz within 3 dB. While a loudspeaker must use a relatively large (often 15" or 18") speaker driver to reproduce low frequencies, headphones can accurately reproduce bass and sub-bass frequencies with speaker drivers only 40-50 millimeters wide (or much smaller ...
^ The average head is about 21.5 cm (8.5 in) from ear to ear. Assuming the speed of sound is 343 meters per second (1125 feet per second), the full wavelength of a tone of 1600 Hz reaches from ear to ear. A tone of half that frequency, 800 Hz, has a wavelength twice as long.
The first-generation AirPods Pro use the H1 chip, also found in the second-generation base-level AirPods. Notable additions include active noise cancellation, transparency mode, automated frequency profile adjustment, IPX4 water resistance, a charging case supporting wireless charging, and interchangeable silicone ear tips.

It also features a 40 mm driver and a frequency response of 10 Hz to 20 kHz. The MDR-7504 and MRD-7502 are similar to the MDR-7506, but with a few exceptions. Both headphones have 30 mm drivers and offer frequency responses of 50 Hz to 18 kHz and 60 Hz to 16 kHz, respectively.
Intentional transmission of sound through bone can be used with individuals with normal hearing — as with bone-conduction headphones — or as a treatment option for certain types of hearing impairment. Bones are generally more effective at transmitting lower-frequency sounds compared to higher-frequency sounds.
This can potentially lead to increased sound exposure as it reduces the signal-to-noise ratio for the mix and causes the musician to increase the levels from the IEM. Active ambient IEMs use external microphones to reproduce the ambient sound in the mix that mimics the frequency response of the open ear and may sound more natural to the performer.
Sound engineers correct the frequency response of a sound system so that the frequency balance of the music as heard through speakers better matches the original performance picked up by a microphone. Audio amplifiers have long had filters or controls to modify their frequency response.
