What do engineers see when they look at a real system or conceive a new design? They will look past the hardware and visualize the flow of energy, where it is stored, and where it is dissipated. They ...

The measure of the output of a sound-producing body stimulated with frequencies over a given RANGE, usually the entire range of hearing (20 to 20,000 Hz). Also called a RESONANCE CURVE. Frequency ...

Let’s start our expla nations of loudspeaker measurement graphs with the most basic graph of a speaker’s behavior: the frequency response. Sometimes this is referred to as the amplitude response as ...

Frequency stability is key to the performance of nanoresonators. This stability is thought to reach a limit with the resonator's ability to resolve thermally induced vibrations. Although measurements ...

The response is nearly 90 degrees out of phase with the excitation and the amplitude of response is large.

One way that Audioholics have presented on-axis and off-axis frequency responses in our loudspeaker reviews are through waterfall plots. Wikipedia defines a waterfall plot as: “a three-dimensional ...
