then you know the problem well: The roar of the engines makes it difficult to hear what's being piped through the speakers -- even when those speakers are situated in
The test involves participants hearing syllables and having to continuously reproduce the rhythm of the syllables. The syllables the participants hear are played at a frequency of 4.5 hertz, which is the average syllabic rate across languages; this basically means that there is room for 4–5 sylla...
So how does your car's AM radio — a receiver — receive the 680,000-hertz signal that the transmitter sent and extract the information (the DJ's voice) from it? Here's how it works./\r\n/ Unless you are sitting right beside the transmitter, your radio receiver needs an antenna to...
How Do Switches Work and What Are Sparks? As you've discovered, if resistance is increased in a circuit, current decreases. If you just break the conductor in a circuit and create an air gap, the magnitude of the resistance for all practical purposes is infinite because air is a good ins...
better overall, and would certainly have a nicer-sounding tweeter, and more accurate bass response. The 8-inch subwoofer may not wow you with its floor shaking power (its bass doesn't reach below 50 Hertz), but this sub will dramatically enhance the performance of many smaller speakers. ...
Once Dirac ART and Trinnov Waveforming are in play, don’t we want our main speakers to go as deep as the lowest room node so we have the ability to actively manipulate the room sound? In that case, since positioning a subwoofer in every region of the room is harder than going with ...
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). A fixed ampl...
Som if your amp provides 500 watts per channel, a pair of speakers rated for 250 watts would be a good fit. Note that the rated output for stereo power amps is usually given on a per-channel basis. A rating of 2x450W indicates that the amp generates up to 450 watts into each of ...
(For more information on tones, see How Guitars Work.) The dial tone sound is simply a combination of 350-hertz tone and a 440-hertz tone, and it sounds like this. Click here to hear a dial tone. You then dial the number using a touch-tone keypad. The different dialing sounds are ...
