What are frequency response curves?
A frequency-response curve of a loudspeaker is defined as the variation in sound pressure or acoustic power as a function of frequency, with some quantity such as voltage or electrical power held constant.
What is the difference between frequency and frequency response?
Frequency Range is the actual span of frequencies that a monitor can reproduce, say from 30 Hz (Bass) to 22 kHz (Treble). Frequency Response is the Frequency Range versus Amplitude. In other words, at 20 Hz, a certain input signal level may produce 100 dB of output.
What is a frequency response curve used for?
Frequency response curves are often used to indicate the accuracy of electronic components or systems. When a system or component reproduces all desired input signals with no emphasis or attenuation of a particular frequency band, the system or component is said to be “flat”, or to have a flat frequency response curve.
What is a good frequency response for speakers?
For speakers, headphones and microphones, ± 2 or 3dB is considered very good. Amplifiers, CD/DVD players and other ‘strictly electronic’ devices should be within ± 0.5 or 1dB at the most.
Is 35 Hz good for a subwoofer?
Headphoneus Supremus. The lower the sub goes, the more power it will take to drive it at a level close to flat. 32Hz is pretty doggone good.
How do you measure frequency response?
The frequency response of a system can be measured by applying a test signal, for example: applying an impulse to the system and measuring its response (see impulse response) sweeping a constant-amplitude pure tone through the bandwidth of interest and measuring the output level and phase shift relative to the input.
What is the magnitude of frequency response?
The frequency response is characterized by the magnitude of the system’s response, typically measured in decibels (dB) or as a decimal, and the phase, measured in radians or degrees, versus frequency in radians/sec or Hertz (Hz).
What does frequency-response curve mean?
Frequency response curves are often used to indicate the accuracy of electronic components or systems . When a system or component reproduces all desired input signals with no emphasis or attenuation of a particular frequency band, the system or component is said to be “flat”, or to have a flat frequency response curve.

What is better frequency response?
A smoother frequency response is better than a highly variable one, with flat being the ideal target. A comparison of an ideal (green), a likely imperceptable real world example (yellow), and more audible (red) frequency responses for speakers.
