※ his is a measured value and not a guaranteed value.
※ Waterproof refers to water resistance in the enclosure.
※ Water resistance is measured by JIS L 1092 Water Resistance Test B method (high water pressure method).
※ Air permeability is measured by JIS L 1092 B method (Gurley method).

■ Acoustic Characteristics (Sound Transmission Loss)

Acoustic Characteristics (Sound Transmission Loss)

※ Sound insulation was evaluated by sound transmission loss (Acoustic Tube Method ASTM E2611-09).
※ The lower the value of sound transmission loss, the better the sound transmission.
