Webcan be in the form of either the direct, early or reverberant sound, however, usually it is the direct sound that is often in most need of reinforcement. In “dry” auditoriums, the reverberant sound can be reinforced, thereby increasing the reverberation time and hence the “liveliness” of the room. WebMay 28, 2015 · This work presents a method to control the perceived distance of an auditory object by changing the directivity pattern of a loudspeaker and consequently the direct-to-reverberant ratio at the listening spot. Control of the directivity pattern is achieved by beamforming using a compact multi-driver loudspeaker unit. A small-sized cubic array …

WebMay 30, 2024 · The direct sound, lateral reflection, and reverberation levels were set to achieve a direct-to-reverberant ratio of 0 dB. With anechoic speech used as source material, the overall sound level at the listening position (“listening level”) was adjusted in the range 20–80 dB in 5 dB increments, subsequently the level of the test reflection ... WebSound in reverberant environments consists of the direct sound component, the early reﬂections, and the late reﬂec-tions. The direct sound is the sound that travels directly from WebReverberation is the accumulation of soundwaves in a space. Because reverberated sounds stack up, they can make direct communication difficult because there is so much ambient sound and the direct sound can get lost. When that happens, people tend to speak up to be heard over the din which only causes more reverb, and the cycle continues. title host of radios first major quiz show

WebReverberation is the reflection of sound in an acoustic environment. Reverb’s character is defined by the number, density, tone and duration of sonic reflections (echoes), which are influenced by a space’s size, shape and surfaces that both reflect and absorb sound.
