As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...

The presentation of loudspeaker measurements varies wildly from manufacturer to manufacturer. This means that, without independent analysis, consumers are left comparing specifications that were ...

Power-spectral plots generated by frequency sweeps or fast Fourier transforms (FFTs) can show you a signal’s frequency content, but sometimes an FFT provides more detail than you need. If you design ...

For decades, many advertisers referenced what became known as the ‘rule of three’: the idea that hearing an ad three times was enough to make it stick. The concept stemmed from early effective ...

Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

In digital broadcasting, video and audio signals are broadcast at low bit rates *2 by employing efficient compression schemes. Audio signals are compressed using so-called perceptual audio coding ...

Replay: Here's a helpful primer on how well our ears measure the sound around us, as well as how changes in frequency, loudness and duration affect perception. By Christian Luther. Our ears are the ...
