Reverberation (commonly shortened to reverb), in acoustics, is a persistence of sound after it is produced. [1] Reverberation is created when a sound or signal is reflected. This causes numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and ...
Babbling in children with autism tends to occur less frequently than in typically developing children, and with a smaller range of syllables produced during the canonical babbling stage. [30] Babbling may also be delayed in individuals who are born with Down syndrome. The canonical stage may emerge two months later for individuals with Down ...
Dereverberation is the process by which the effects of reverberation are removed from sound, after such reverberant sound has been picked up by microphones. Dereverberation is a subtopic of acoustic digital signal processing and is most commonly applied to speech but also has relevance in some aspects of music processing.
Similarly, the trigger for episodes of crying in patients with PBA may be nonspecific, minimal or inappropriate to the situation, but in depression the stimulus is specific to the mood-related condition. These differences are outlined in the adjacent Table. In some cases, depressed mood and PBA may co-exist. Since depression is one of the most ...

A speech sound disorder (SSD) is a speech disorder affecting the ability to pronounce speech sounds, which includes speech articulation disorders and phonemic disorders, the latter referring to some sounds not being produced or used correctly.
After determining the best dimensions of the room, using the modal density criteria, the next step is to find the correct reverberation time. The most appropriate reverberation time depends on the use of the room. RT60 is a measure of reverberation time. [9] Times about 1.5 to 2 seconds are needed for opera theaters and concert halls.
