A typical characteristic of a 2-way speaker is that at the crossover frequency, due to the physical distance between the centres of the woofer and tweeter, the sound that emanates from the combination is not omni-directional, but lobed. Within the region of the lobe the sound level, at the crossover frequency is much higher as compared to ...
The ratio between two acoustic pressures in deciBels is expressed by the equation dB = 20log(p1/p2), so for every doubling of distance from the point source p1 = 1 and p2 = 2, thus there is a sound pressure decrease of approximately 6 dB. A line source is a hypothetical one-dimensional source of a sound, as opposed to a dimensionless point ...
In a reverberant space, the sound perceived by a listener is a combination of direct and reverberant sound. The ratio of direct sound is dependent on the distance between the source and the listener, and upon the reverberation time in [the room]. At a certain distance the two will be equal. This is called the "critical distance."
If the two output buses are to remain stereo then a law of −3 dB is desirable. A law of −4.5 dB at center is a compromise between the two. A pan control fully rotated to one side results in the source being sent at full strength (0 dB) to one bus (either the left or right channel) and zero strength (− ∞ dB) to the other.
If a sound source and two microphones are arranged in a straight line, with the sound source at one end, then the following can be measured: The distance between the microphones (x), called microphone basis. The time of arrival between the signals (delay) reaching the different microphones (t). Then v = x/t.
The center channel also anchors the sound field, eliminating phantom images such as those that plagued early matrixed quadraphonic sound if the speakers were not precisely placed. [2] The center channel eliminates the need to create a phantom center with left and right stereo speakers. The center channel provides image stabling effects and is ...
3D sound localization refers to an acoustic technology that is used to locate the source of a sound in a three-dimensional space.The source location is usually determined by the direction of the incoming sound waves (horizontal and vertical angles) and the distance between the source and sensors.
The bandwidth is the distance between the upper and lower cut-off frequencies, and is the range of frequencies passed by the filter. The shape and organization of the basilar membrane means that different frequencies resonate particularly strongly at different points along the membrane.
