Student Sleep Chamber

Product Description

Student Sleep Chamber

• No noise in the classroom, even when 8 experiments are running simultaneously
• Measurement of the sound intensity level using a sound level meter
• Study of the sound attenuation obtained with different materials
• Checking the decay of the sound acoustic intensity according to the distance
• This briefcase, lined with sound insulation, allows to confinate the sound and to have the students perform experiments on the sound at the same time.
• The sound source integrated into the case, a stand-alone buzzer on a battery, is equipped with a detector that can cut the generation of sound when opening the case. Cela avoids disturbing the experiences of other students when opening the case to study the sound
• attenuation of another material.
• Two wall passages allow introducing the microphone of the sound level meter in the room deaf.
• The case is delivered with a set of screens of different materials and thicknesses to compare their absorbency.
