📃 Оригинальное описание:
In this video, I’m clapping my hands in a big hall. The black surface is acoustically absorbent material. Even though it covers about 80% of the walls, the reverberation time in the space is very long. This is because of flutter echoes between the lower untreated parts of the parallel walls.
After recording this video, I have metrologically assessed the space in more detail by measuring the room impulse response with a class-1 sound level meter as part of my work as an acoustical consultant. BKL, the company I work for, offers world-class sound and vibration monitoring, diagnostics, predictions and assessments to recognized standards and guidelines. We guarantee the highest quality of acoustical services available.
The video was recorded in February 2021, near Vancouver in Canada.
