WebDirect Sound is the region in which the sound measured can be attributed to the source alone without reflections. Early reflections that reach the listener within 50 ms integrate with the direct sound and can improve speech clarity. However later reflections may have a negative effect on the clarity ...

WebThe total sound field of room acoustics is divided into the direct sound field and the reverberant sound fields by a further subdivision into useful and detrimental parts. The useful part includes the sound waves which the human ear can identify as part of the direct sound and of the first sound wave respectively. According to experiments the
