Time delay and reverb to simulate the signal characteristics of the sound room sound field of special equipment

. In the recording program production, the time delay and reverb can simulate the sound field of the art delivery time, space, direction, distance and other important information, and can make some special effects. Time delay and reverb are psychoacoustic nature of the work scope, its control techniques are

Sound Aesthetics. It can be said, time delay and reverb is the art of concocting the main equipment essential to the sound field. Because of this, time delay and reverb on the use of sound processing equipment than other complex and flexible. For beginners on the time delay and reverb understand the nature of work, it is necessary to talk about the interior sound field, introduces the basic concepts of room acoustics and the relationship with the person's hearing in order to understand the principles behind the work described and regulation skills.

An indoor sound field sound Both teaching and concert halls, theaters, and even the small recording studio or large room, all indoor listening environments, the existence of sound energy are combined into a three-part voices, this is from the geometrical acoustics point of view, the use of imaginary lines that sound propagation direction and path of the assumed voice mode. In fact, the sound does not go straight.

After 10 ~ 20ms time (T1), after interval, close to the surface from early reflections to reach the listening point, this is the first sound reflections. Another little later time, after the interval to reach listening point T2 is the second reflections. Then T3, the third time reflections. Perhaps there will be reflection from the other adjacent to the sound reflector, we call this part of the sound of early reflections, often early reflections within the 35ms completed in the early reflections is about 20 ~ 50ms after the time for reverberation to enter time. With the passage of the acoustic radiation to the numerous reflective surface, appears more and more reflections. Silk then reflected sound very close, almost overlapping each other can not distinguish the respective components, this part of our mess, unable to distinguish between the delay reflected sound, called the mixed sound.

There is a curve from left to right, this is the reverberation curve to end the whole process of the establishment. When the reverberation from the entry to the stable state, that is, maximum, gradually decreases until it disappears to zero, this process is called reverberation process, but this is not what we usually reverberation time. From the statistical point of view the theory of acoustics, reverberation time, the objective characterization of room acoustics parameters. It's measured approach is to start from the maximum sound pressure attenuation 60dB when the number used to indicate the length of the reverberation time. Then, after the T60 is still a reverberation time why not included? Comparing this curve as steep T60, and T60 level behind the curve, so that calculation say accurate.

In addition, the curve drawing mixed with the sound of the past, said the painting is different. This is because the real room reverberation is not in the early reflected sound for some time after the first gap suddenly appeared. The establishment of the reverberation sound diffusion in the absence of rules in the progressive, this curve can be expressed through the reverberation of the establishment, maintenance and decline process.

Indoor sound field in the direct sound, early reflections, in any part of the sound mixing sound has its own role and constitutes the entire sound field differently. This is one of our issues to be discussed below.

II and hearing room sound field

1, the human ear to sound direction, from a high degree of perception

Normal ears on the field of sound effects are perceived and judged. This includes physical and psychological double reflected. First is the sound source with horizontal orientation (horizontal positioning) the perception and judge. For example, people left low-frequency sound source, in the right location-aware, mainly depends on the intensity of the sound reach the ears poor judgments; and people from the sound source location (vertical orientation) are perceived and judge. This is mainly relying on direct sound and reflected sound in recent times and the mixed ratio to determine the perception of sound. For example, the direct sound intensity, sound and mixing sound weak reflection in the large proportion of direct sound from the past can be judged; while the proportion of hours of direct sound, clarity decreased, we can determine the distance. Third, people high sound positioning (elevation positioning), in a certain range have to judge the role. A high degree of localization is the use of binaural hearing to determine the spectrum difference out subconsciously. For example, due to suppression of different angles, on the perception that the human ear different frequency characteristics curve, and hear the sound image in front of comparison, to determine elevation. Normal human ear can be judged to 200 100 a high degree of sound location.
