Question

Explain the principle of accoustics and accoustical defects

Answer 1

COMMON ACOUSTICAL DEFECTS

Acoustical conditions in a big room, ball or auditorium etc`. areachieved when there is clarity of sound in every part of me occupiedspace.

For this, the sound should rise to suitable intensity everywhere withno echoes or near echoes or distortion of the original sound ; withcorrect reverberation time.

COMMON DEFECTS :

(1) Reverberation(2) Formation of echoes(3) Sound foci(4) Dead spots(5) Insufficient loudness(6)External noise

Answer 2

Acoustical conditions in a big room, ball or auditorium etc`. are achieved when there is clarity of sound in every part of me occupied space. ... Reverberant sound is the reflected sound as a result of improper absorption.An important part of a good and healthy indoor climate is efficient sound absorption. ... Troldtekt is known – and renowned – for its excellent sound absorption properties, which help to reduce noise and create good acoustics in every room.

An important part of a good and healthy indoor climate is efficient sound absorption. It is an important factor in schools, kindergartens, sports centres and work places where the noise level can be considerable.  

A high level of noise over a short or long period of time can influence the well-being of those who use the facilities and lead to health conditions. Worst case, it could lead to irreversible hearing damage.  

Troldtekt is known – and renowned – for its excellent sound absorption properties, which help to reduce noise and create good acoustics in every room.
