A frequency response is a visual representation of how well an audio component reproduces the audible range of sound. It’s usually presented as a line graph, with the device’s output amplitude on the y-axis (in decibels) plotted against frequency on the x-axis (in Hertz).
Frequency response can be defined as the measure of a system’s output spectrum in response to a stimulus, often represented as a function of frequency. For instance, if you play a tone at a specific frequency through a speaker, the frequency response will indicate how well that speaker reproduces the sound at that frequency.
For many speaker designers, the speaker frequency response is considered the most important characteristic of a speaker. Speaker frequency response is the measure of a speaker’s ability to reproduce different frequencies or pitches.
Frequency Response attempts to describe the range of frequencies or musical tones a speaker can reproduce, but it should not be the only thing you look for. What you need to know about understanding frequency response curves of loudspeakers.
This article will talk about what frequency is good for speakers and answer some questions regarding frequency response in speakers.
We measure these variations in the speaker's output--its frequency response--with the decibel (dB), a unit of relative volume, 1 dB being the smallest change in volume that most of us can detect. A difference of 3 dB is quite noticeable.
A speaker's frequency response accuracy tells you how it reproduces sound from the low-bass range to the high-treble range. Depending on the audio content you listen to, you may focus on different aspects of frequency response accuracy.
What Is Frequency Response? The frequency response of a speaker, a microphone, or a pair of headphones describes the device’s ability to pass audio frequencies from its input to its output. Some devices will pass all frequencies from input to output evenly.
The frequency response of a speaker is a crucial characteristic that sets it apart from others. It’s the pattern of magnitude (loudness) and phase (timing) that the speaker produces across different frequencies.
So, what is frequency response’s role in the sound quality of headphones or speakers? Ideally, speakers and headphones should have a reasonably flat frequency response. You want the frequencies of the input signal to be unchanged when played back through your speakers or headphones.
