Fundamental science
Watch an enclosed sound source while the air pressure in the transparent chamber changes.
THE PRODUCT IN MOTION
Sound transmission through air weakens as the available air is reduced. Some vibration can still travel through supports, so a practical demonstration need not become completely silent.
Video & text guideTHE ACTIVITY & MECHANISM
Listen to the enclosed sound source, then use the labelled air-removal control and compare the sound with the pressure indication. Sound needs a material medium to travel. Reducing the air weakens this transmission path, while some vibration may still reach the surroundings through the apparatus supports.
Start the enclosed sound source and listen to the initial sound.
Use the labelled pump control and observe the pressure indication.
Compare the sound and visible source motion as the air is removed.
REFERENCE & PROJECT SCOPE
The photographs show a project configuration. Confirm the complete installation envelope, interfaces and operating instructions for the version to be supplied.
Project drawing reference for the circular cabinet and transparent upper dome, including the base. Values are approximate project-planning references until the final supplied configuration is agreed.
BEFORE AN ENQUIRY
24 months of complimentary spare-parts support, remote technical guidance and long-term after-sales support. Exhibit Engineers pays the shipping cost of complimentary spare parts during the 24-month support period.
Explore the supportYes. Prototype testing and sample fabrication are available for custom projects. Discuss which functions or features you need to review for your version. The scope, cost and schedule are agreed for the project.
How prototype testing & samples workYes. The gallery and video use company-provided photographs and recordings. Project drawings are identified separately.
