SoundEar 2 Outdoor Industrial Noise Warning Sign

Applications

The SoundEar 2 Outdoor Industrial is ideal for noise warning in wet and dusty environments.

Outdoor Noise Warning

The weatherproof noise sign can be mounted on a wall in an area of varying noise levels. It is particularly helpful in areas where the noise levels are only occasionally high, so people know when to take action to reduce the levels or protect their hearing.

It will continuously measure the sound levels using its built-in microphone and light up to warn when the levels are too high and it is time to take action.

Indoor Noise Monitoring

This version of the SoundEar noise warning sign is also perfectly suited to indoor installations. In dusty industrial areas the enclosure keeps the noise warning sign itself clean and free of damage.

You may even choose to use this version of the sign for the extra physical protection it offers. It is more securely mounted to the wall than the standard SoundEar.

Construction Noise

Mounted in and around a construction or building site, the SoundEar becomes an important part of a noise control plan. It can be difficult to know when equipment is making too much noise, especially if you are exposed to it day after day or you are wearing hearing protection. The SoundEar measures the noise and, unlike the human ear, doesn't suffer from a varied perception.

Installation and Setup

Installation of the SoundEar 2 Outdoor consists of two parts: mounting it on the wall and setting up the trigger level.

Wall Mounting

With the front cover of the enclosure removed there is access to four mounting holes through which the sign can be fixed to the wall.

Power

Power is provided to the outdoor noise warning sign by a 24 VDC adapter, which is included. The power adapter should be mounted indoors (it has no weather protection) and connects to the noise warning sign via a 10m extension cable, which runs through a gland directly into the base of the noise sign enclosure.

Setting Up - Trigger Levels

You need to choose the level at which you want the noise sign to light up. In some situations this can be done by trial and error. Set a level and see if that works, adjusting as necessary. A more scientific approach would be to use a sound level meter to measure the sound level at the position of interest and then adjust the noise sign to light up accordingly.

To prevent tampering, the front cover has to be removed using a screwdriver to access the dial that sets the level.

Noise Warning Displays

The SoundEar 2 has three main display components in the shape of a standard hearing protection symbol:

• Green light - Indicates that the sign is monitoring. Reminding people to keep the noise levels down.
• Yellow warning light - Warns that the sound levels are getting close to the limit.
• Red warning light - Indicates that the noise is too high.

You choose the sound level at which the red light comes on. The yellow warning light comes on 5 dB below the red light.
