IASCA - International Auto Sound Challenge Association |
| • |
ICE - Acronym for In Car Entertainment |
| • |
IIR Filter - (Infinite Impulse Response Filter) A digital filter employing a single stage, through which the signal is passed repeatedly to achieve the desired processing effect. Offers simplicity of design and lower cost than the FIR type. |
| • |
Image Rejection - The rejection of the same signals that can be received
at two or more points on the dial of a tuner by a single radio station (ghost, images) . Image
Rejection is expressed in decibels, the higher the number the better. |
| • |
Imaging - The reproduction of sound accurately so that the listener can
imagine the original environment and placement of the original sound sources accurately within
within that environment. The better the imaging the more analogous the reproduced
sound will be to the original. |
| • |
Impedance - The opposition to the flow of alternating current (AC) in a circuit.
Measured in ohms  . |
| • |
Inductance - The ability to induce an electrical current. Measured in Henrys. |
| • |
Inductive Coupling - Radiated noise that is transmitted through a magnetic field to surrounding lines. |
| • |
Inductor - An electrical component in which impedance increases as the frequency of the AC decreases. Also known as coils that are used in passive crossovers. Inductors are rated in Hennes. |
| • |
Infinite Baffle - A loudspeaker baffle of infinite space that has no openings for the passage of sound from the front to the back of the speaker. Also, a sealed enclosure where the internal volume is greater than the Vas of the driver. |
| • |
Input Sensitivity Control - Adjusts the amount of input signal being fed to the
amplifier stage to reduce distortion. |
| • |
Insulation - A material that electrically isolates a conductor
or thermally isolates an object from its surroundings. |
| • |
Intermodulation Distortion (in loudspeakers) - Is the distortion generated
in single cone speakers when the cone is reproducing a high and low frequency
simultaneously. The high frequency peaks will be flattened off if the low frequency is
distorted in any way. |
| • |
ISO-DIN Mounting - Refers to a mounting system in which the headunit is mounted behind the dash panel with side brackets, employing factory installed trim panels. |
