The extra space above one's head so that there will not be a problem walking around. The extra signal room in an electronic circuit to prevent slight over levels from being clipped and distorted.
Also referred to as Dynamic Headroom. An amplifier's ability to go beyond its rated average power for a short time in order to recreate loud or explosive audio signals that rise very quickly.
Level between average signal levels and maximum peaks without clipping.
1. In video, the room that should be left between the top of a person's head and the top of the frame when composing a clip. 2. In audio, the amount of available gain boost remaining before distortion is encountered.
The measurement in decibels (db) above 0 db a piece of equipment can process before clipping.
The amount of room between the normal operating level and the maximum level where clipping (distortion) occurs in a sound system. This number tells you how much louder the system can get before it goes into distortion.
1) The difference (expressed in dB) between the normal operating level and clipping level of an amplifier or audio device. 2) In recording, the difference between a normal tape operating level and the level where the distortion reaches 3%.
the capacity of a system to reproduce loud sounds without distortion
Expressed in decibels (dB). High frequency headroom means that the amplifier cannot be easily overloaded. A measurement based on the amount of reserve power available at a given time.
is the space between the warning bar and the amplitude where signal clipping begins to occur.
The safety margin in dB between the highest peak signal being played through a piece of audio equipment, and the absolute maximum level the device can possibly handle.
The difference between the maximum, or peak, signal levels in a program, and the maximum level that the audio component is capable of. E.g. a movie sound track requires 100 watt peak output to satisfy a listener, but the listener is using a 200 watt power amplifier. There is 100 watts of headroom. Headroom is inaudible, but it is there in case it is needed. See: Loudness.
A term related to dynamic range, used to express in dB, the level between the typical operating level and the maximum operating level (onset of clipping). For example, a nominal +4 dBu system that clips at +20 dBu has 16 dB of headroom.
The ability of an amp to deliver more than its rated power for short durations. This capability allows an amp to reproduce musical peaks as though it were a higher power amp
1) The level difference (in dB) between normal operating level and clipping level in an amplifier or audio device. 2) A similar level difference between normal tape operating level and the level where the distortion would be 3%. 3) The difference, in decibels, between the peak and RMS levels in program material.
Headroom is the voltage difference between the peak of the 50/60 Hz power line sine wave voltage and the ‘Threshold voltage" of the MOV (or other) suppression elements. A minimum spacing of 15% above the sine wave peak is considered essential.
Difference between the absolute maximum level and th enominal operating level.
The amount of additional signal above the nominal input level that can be sent into or out of an electronic device before clipping distortion occurs.
The output capability an amplifier before it distorts its output signal.
The ability of an amp to go beyond its rated power for short durations in order to reproduce musical peaks without distortion. This capability is often dependent on the power supply used in the design.
the margin of safety (usually expressed in decibels) between nominal operating levels and a signal-overload condition.
Technical jargon for the safety margin allowed for peaks in volume without distortion.
Expressed in dB, the difference between the highest level present in a signal and the maximum level an audio device can handle without noticeable distortion.
A term that has spilled over into music- computing from the recording industry. Headroom was the gap between the peak working level on tape and the point at which the sound might actually distort. In computer parlance 'having the headroom' means having sufficient spare computing power.
The amount of gain an amplifier can produce before distorting.
the difference between the highest signal possible without distortion and the average signal level through a system
