What can be done to improve telephone service in a noisy environment?

Dealing with noise is a progression. Noise reduction is standard on all of Guardian’s telephones.

All Guardian Telecom telephones can be equipped with noise cancelling microphones. (The EXT-401 Explosion Proof Telephone is the only exception.)

The next step is volume adjustment. Several methods are available depending on the telephone model.

• Adjustment by buttons on a membrane key pad
• Adjustment by volume up and down switch on a handset
• The EXT-401 has a volume control button option.

If noise levels still make it difficult the final step is an Acoustic Booth. Guardian has a selection of AB-100 or AB-1000 models with up to -25 dB of sound deadening capabilities depending on the interior liner type.
