In the audible range frequency response is usually referred to in connection with electronic amplifiers, microphones and loudspeakers. Radio spectrum frequency response can refer to measurements of coaxial cable, twisted-pair cable, video switching equipment, wireless communications devices, and antenna systems.
The frequency F s and the frequencies above and below it where the impedance is 1 / √ 2 Z max are important in determining the loudspeaker's T/S parameters. These can be used, for example, to design a suitable enclosure for the driver, especially for low frequency drivers.
While the very best modern speakers can produce a frequency response flat to ±1 dB from 40 Hz to 20 kHz in anechoic conditions, measurements at 2 m in a real listening room are generally considered good if they are within ±12 dB.
Frequency response (FR) This measurement tells you over what frequency range output level for an audio component will remain reasonably constant (either within a specified decibel range, or no more than a certain number of dB from the amplitude at 1kHz).
A tweeter or treble speaker is a special type of loudspeaker (usually dome, inverse dome or horn-type) that is designed to produce high audio frequencies, typically deliver high frequencies up to 100 kHz.
Examples of typical loudspeaker measurement are: amplitude and phase characteristics vs. frequency; impulse response under one or more conditions (e.g. square waves, sine wave bursts, etc.); directivity vs. frequency (e.g. horizontally, vertically, spherically, etc.); harmonic and intermodulation distortion vs. sound pressure level (SPL) output ...
exemplary frequency response (both in amplitude and phase) [citation needed] because the principle of generating force and pressure is almost free from resonances unlike the more common electrodynamic driver.
Frequency range and frequency response. The frequency response specification of a speaker describes the range of frequencies or musical tones a speaker can reproduce, measured in hertz (Hz). The typical frequency range for a subwoofer is between 20–200 Hz.
Some full-range speaker systems are designed with limited-range drivers, and must be used with equalizers to flatten and extend their frequency response, while others achieve acceptable response without electronic assistance. There are full-range speaker systems using up to 15" single drivers. [4]
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
