MAGNETIC SHIELD ROOM WITH RESONANCE REDUCING STRUCTURE

PROBLEM TO BE SOLVED: To provide a magnetic shield system with a resonance reducing structure, capable of providing an ultra-faint magnetic noise space making a noise level of a magnetic noise lower by single or double digits than ever, by reducing resonances which are not conventionally assumed to...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a magnetic shield system with a resonance reducing structure, capable of providing an ultra-faint magnetic noise space making a noise level of a magnetic noise lower by single or double digits than ever, by reducing resonances which are not conventionally assumed to exist at all and which belong to a non-audible frequency band, generated from an air conditioning duct.SOLUTION: A magnetic shield room 10 is connected to an air conditioner 20 via an air conditioning duct 30 formed of a flexible non-magnetic material. The air conditioning duct 30 is provided with a side branch 40 which is a resonance type silencer for reducing resonances in a non-audible frequency band, generated from the air conditioning duct 30 resonating with vibrations of the air conditioner 20, and which is formed of a non-magnetic material.
