ABSTRACT:
The present invention provides a sound collector preferably applicable to an acoustic analysis with a high degree of accuracy and includes a sound collection hood having an opening at the front end and a sound reflective inner wall shaped like a rotating surface having a focus behind the opening at least provided on the opening side, thus forming an inner space, a microphone placed inside the sound collection hood with at least a sound receiving face oriented forward for receiving a sound wave entering the sound collection hood and an acoustical absorbent body formed in front of the sound receiving face so as to form an incident path for sound to enter the sound receiving face and in a shape surrounding the incident path.
