Apart from decibels (see number 4 in this list), the watt is the most commonly used term to describe the power of a system. Specifically, it refers to the power that an amplifier delivers to a speaker. As a measure of the volume of a system, it’s meaningless without knowing more about the speakers, but in general it’s safe to assume that the more w...
Headroom is the amount of power (in watts) that an amplifier holds “in reserve” to deal with brief spikes in signal. Headroom is why you always want to overestimate the wattage you need, in case the system encounters a sudden surge (for instance, from someone plugging in a microphone without turning down the volume). For maximum headroom, and safet...
Clipping is the popping, distorted sound that means an amplifier is exceeding its power output. When clipping occurs, especially for an extended period of time, odds are you’re damaging your amplifier, speakers, or both! Again, choosing an amp with adequate headroom (and speakers rated for the proper wattage) will help alleviate this problem.
Named after Alexander Graham Bell, a decibel (dB) measures the relative loudness of a sound as it arrives at the eardrum. As stated in our glossary, “a difference of approximately 1 dB is the minimum perceptible change in volume, 3 dB is a moderate change in volume, and about 10 dB is an apparent doubling of volume.” In general, a whispered convers...
Technically, the dynamic range of audio content is the difference in decibels between the loudest and softest moments. In audio, it refers to how big of a change the amplifier (or other component) is able to reproduce before it distorts. Dynamic range shouldn’t be confused with frequency range, which measures a speaker’s ability to reproduce both l...
Gain is the ratio of the input signal to the output signal. In short, it’s a fancy word for volume: increase the gain, and the sound gets louder. On PA systems, the gain control functions the same as a volume knob for an input source such as a microphone. Turn up the gain on your mic, and you will turn up the mic’s volume. Though, if you increase t...
Feedback is the screechy sound that occurs when a microphone gets too loud or gets too close to the output speaker. The output gets “fed back” into the microphone, is amplified through the speaker, gets picked up again, and the process continues until the all-too-familiar feedback squeal kicks in. Or, to quote AudioLinks’ glossary: “A signal is rec...
Impedance is a measure of electrical resistance specified in Ohms. When choosing speakers, it’s important to match the impedance of the speaker to the rating of the amplifier for maximum performance. In the case of some impedance mismatches, you can damage your gear, so it’s critical to pay attention to this specification. Fortunately, manufacturer...

Aug 10, 2022 · It turns out there are a couple of ways to define a sound. One type of sound is a relatively narrow passage of water between the mainland and an island. It's also an inlet, bay or recessed portion of the ocean. Currituck Sound certainly fits those definitions. So does Pamlico Sound, as well as Puget Sound in Washington.
