Wood Equalizer Acoustic Panels are highly effective in public spaces. Cinemas, theatres and auditoriums are examples of spaces which require perfect acoustic conditions. Too long reverberation time makes it difficult for the audience to understand actors, and for the students to hear a lecturer. These acoustic issues are causes of many voice disorders. It has been proven that a lecturer must speak up to 6db lauder in an unadapted room, in order to be properly heard. In the long run, such high level of voice emission, can be harmful to health. For that reason Wood Equalizer Acoustic Panels are a perfect solution in classrooms, conference rooms, lecture halls, offices, clubs - in any place where simultaneously many people conduct conversation or/ and additionally music is played. Acoustic panels allow speaking without rising voice to the accompaniment of music. Panels fitted on walls and ceiling additionaly improve the appearance of any interior. The effectiveness is guaranteed by the high absorption coefficient α=0,55 and NRC=0, 70 ( Noise Reduction Coefficient ).
Sound absorbing properties of Wood Equalizer Acoustic Panels have been confirmed by accredited acoustic tests carried out by Building Research Institute ITB. Measurement of absorption coefficient α (alpha) was conducted in accordance with the international standard PN-EN ISO 354:2005. The avarage absorption coefficient α for Wood Equalizer Acoustic Panels is α=0,55. Additionally noise Reduction Coefficient was calculated: NRC=0,70. The graph shows the value of α for a given frequency.
