Chapter 1 Room acoustical design
The listening room is a small room, its acoustic characteristics, and large halls are significantly different.For the room sound quality, the scale of the room close to or at the wavelength of the recording and listening band low-frequency side, a small https://www.51lunwen.org/mediamanagement/2012/0621/1653283258.html room.The acoustic characteristics of the small room to put the audio and sound quality to reduce the impact is significant.Therefore, the room's acoustic characteristics, the design must have a clear difference of the small rooms and large halls.In addition to the general sound design principles, but also consider their uniqueness, and well implemented in the sound processing, so as to make the listening room with good acoustics.Small room sound quality mainly in the low frequency sound system playback frequency range of the low-end reached 20Hz, but mature auditorium acoustics design techniques only take into account the 125Hz.Therefore, it is necessary to further analysis of the lower band of the acoustic characteristics of well research methods to control its sound quality.The small room sound field at low frequencies is characterized by strong standing-wave resonance, https://www.51lunwen.org/mediamanagement/ the transmission response of its rooms, spatial characteristics and temporal characteristics have an impact.The parameters of the corresponding impact sound transmission response, the distribution of indoor sound pressure level and reverberation decay properties of these parameters is determined by the room volume, shape, and side length ratio as well as sound absorption material layout.
Often used in a large hall reverberation time to describe the uniform decay of sound energy in the room, small room low frequency reverberation time is closely related to the concept of decay of the low-frequency normal modes, it is not the reverberation time of the original concept, but the classic mixedproject extended reverberation time.Correctly describe the low-frequency attenuation of the small room should adopt the concept of fluctuations in the description of each normal modes decay.The room volume is small, the number of low-frequency simple positive wave of each frequency distribution of normal mode uneven, the normal mode damping, its decay rate is also different, therefore, two adjacent frequency of simple positive wave in the decay process will produce interference effects.Sometimes hear the original excitation frequency of the room adjacent to the normal mode of decay rather than the decay of the original sound signal.
