About This Product
Air is drawn out of the vessel through its outlet using a vacuum pump, which is not included. With no air to transmit the sound to the vessel walls, the buzzer becomes quieter, while the foam mounting reduces the sound passing to the walls through the buzzer's support.
Frequently Asked Questions
Q1. Is a vacuum pump included with the Buzzer in a Vacuum Vessel?
No. The vessel has an outlet for evacuating the air, but the vacuum pump is not included.
Q2. Why does the buzzer get quieter?
When the air is evacuated, there is no air through which the sound is transmitted to the walls of the vessel, so the sound is attenuated.
Q3. Why is the buzzer mounted on foam?
The foam reduces transmission of sound to the vessel walls.
