Industrial Noise Sign Overview

The SoundEar 4 is the top of the Industrial range of noise warning signs, with advanced display configuration, measurement storage and WiFi network connection.

This version of the SoundEar Industrial is ideal for carrying out long term noise checks but also giving an instant and clear warning of high noise levels.

Instant Warning

The SoundEar 4 Industrial is usually set up to let people know that the sound levels are getting high, with the red light coming on when action needs to be taken - either reduce the levels or use hearing protection. There are many ways to configure this version of the noise sign. Please visit the Displays section for more information.

Each of the lights (green, yellow, red) can be configured to come on at different levels. A common setting would be to have the green light on all the time, to remind people that the sound levels are being monitored, the yellow light could be set to light up when the surrounding noise is 80dB(A) and the red light flashing when it exceeds 85dB(A).

Exposure Indicator

A bar of lights on the left side indicate the noise exposure level over the last 10, 15 or 60 minutes.

Data Logging and Software

The SoundEar 4 Industrial has a large internal memory that stores the sound level every minute. When downloaded to a computer this gives a detailed graph of the noise throughout the day. The measurements can be accessed from the software over a WiFi connection or a USB memory stick can transfer the noise measurements from the SoundEar to a computer.

External Microphone

The SoundEar 4 Industrial has a plug-in microphone. It connects at the bottom of the sign and remains out of sight and out of harm's way. If you need to mount the microphone away from the sign then you can use a microphone extension cable, which should be ordered separately, order code SE4EXT.

Outputs and System Integration

The SoundEar 4 Industrial can also output data over a Modbus TCP interface for integration with other systems. Please contact NoiseMeters for more information about this.

Applications

The SoundEar 4 Industrial is designed for high noise level warning and long term monitoring in industrial areas. Due to its attractive design, this noise sign is especially suited to areas where a typical "industrial" product won't fit in.

Non-Industrial Applications

For other environments such as hospitals, libraries and offices, the standard SoundEar 4 Noise Warning Sign may be more suitable. It has the same capabilities but displays the noise warnings with an ear symbol rather than a hearing protection symbol.

Noisy Factory or Industrial Site

Mounted on factory walls, the SoundEar 4 Industrial can warn workers that the noise levels are too high and that it is time to take action - reduce the noise levels or fit hearing protection.

This instant alert of high noise levels is ideal for factories with intermittent noise levels. Rather than leaving employees to guess when to take action based on their own perception of the noise levels, it is better to clearly show the real acoustic situation.

Taking advantage of the data logging facility and software (both included with the SoundEar 4 Industrial) you can check the noise levels throughout the day, identifying the noisiest periods.

Installation and Setup

Installation of the SoundEar 4 Industrial consists of two parts: mounting it on the wall and setting up the display.

Mounting - Single Screw

The easiest way to mount the noise sign on the wall is using a single screw and hanging the sign, just like a picture.

Optional Mounting Brackets

For a more permanent mounting, angled viewing and corner mounting you can use the optional VESA mount (order code SE2VESA). The mount is first fixed to the back of the SoundEar Noise Sign and a VESA mounting bracket is fixed to the wall. The Noise Sign and mount are then fixed to the wall bracket.

We also provide a bracket to mount the SoundEar to a 30 to 50 mm pole (order code SE2VESAP).

Power

The SoundEar 4 Industrial comes complete with a USB-C plug-top power adapter. This provides the safe low voltage that the noise sign requires.

Location and Sound Level

The perfect location for a sign depends on the layout and the acoustics of the area in question. In large areas, or where the acoustic environment varies considerably, multiple signs should be used to ensure good coverage. A quick survey with a sound level meter (such as the one included in the multi-packs) can help determine the ideal locations.

If the signs are being used to warn about a risk to hearing then it is not always just a simple case of setting it to 85dB(A). The sound level at the mounting point on the wall will be a little away from machinery and will probably suffer from reflections. Ideally it should be adjusted to light up when the noise levels where people are working approach the acceptable limit.

Setting Up - Trigger Levels

The SoundEar 4 Industrial can be configured in many ways, with different trigger levels for the green, yellow and red lights, as well as different trigger durations and minimum lighting periods. It can also be set to have different settings for night time and will switch to those at the set times.

While some of the configuration can be carried out using the controls on the front of the sign (four arrow keys), it is often more convenient to use the software. There are two ways to do this:

  • Connect the sign to the computer's USB port and configure it directly.
  • Save the configuration to a USB stick, which will then configure any SoundEar 3 that it is plugged in to.
  • Connect to the sign over WiFi

In this example the Red light is set to flash when the sound levels are above 60dB for at least 0.5 seconds. It will flash for at least 3 seconds.

Noise Warning Displays

The SoundEar 4 has five main display components:

  • Green light - Usually used to indicate that the sign is monitoring, it can also be set to come on at a programmable sound level.
  • Yellow light - Usually used to warn that the sound levels are getting close to the limit, also individually programmable to a sound level.
  • Red light - Indicates that the noise is too high. This is also programmable with its own trigger level.
  • Digital display - Can be set to show the current sound level or the average sound level over a given time. Otherwise it can be set to show the time or switched off altogether.
  • Noise exposure indicator - Indicates the accumulated noise exposure over the last hour, 15 minutes or 10 minutes depending on configuration.

You can have two different time periods set, so you can have it operating with one configuration during the day and another during the night. It will switch between these settings at the times you select.

No matter what the display is showing, the SoundEar 4 Industrial is still monitoring and logging the sound levels. It could even be left showing just the time or nothing at all, thus avoiding people shouting or whistling to see it react.

Example Displays

As each indicator (green, yellow, red) can be set to light up at different levels and can the red light can be set to be constant or to flash, there are many different configurations possible. Here are some examples.

1. Dual Level Warning - The most common configuration. The Green light is on all the time to remind everybody that the noise levels are being monitored. In this example the green light is always on to show the sign is monitoring, the yellow comes on at 75 dB(A) and the red at 80 dB(A)

2. High Impact Flash - For maximum impact when the threshold is passed, the red light can be set to flash. In this it starts flashing at 80 dB(A).

Noise Exposure Indicator

The main part of the SoundEar Industrial noise warning sign indicates the current sound level, lighting up yellow and then red as soon as high noise levels are detected. In an industrial environment it is also important to look at the longer term noise exposure levels.

The Exposure Indicator on the left side of the noise warning sign gives workers key information about their recent noise exposure. It calculates a rolling average over a selectable period of 10, 15 or 60 minutes. Using green, yellow and red indicators, the exposure bar helps workers understand their recent noise exposure and make more informed decisions about when to wear hearing protection, particularly during longer periods in noisy environments.

Green lights at the bottom of the bar show that the noise levels are well below the threshold, which can be configured by the user. The yellow lights show that the exposure is getting closer to the threshold. When the threshold is reached the indicator bar goes red.

Software

For long term monitoring of the noise levels in a factory, the SoundEar 4 Industrial stores the sound levels for download to a computer. The software is included with the noise sign and offers:

  • Display live results
  • Configure the noise sign
  • Trigger level and timings for each light
  • Data logging settings
  • Digital display settings
  • Download measurements
  • Plot graphs of the sound levels

The software is included with the SoundEar 4 Industrial at no extra charge and is designed for all recent versions of Windows. It communicates with the sign via the computer's USB port or WiFi network. If a WiFi network is not available then downloads and configuration can be carried out via a memory stick, so you don't have to take the sign down from the wall each time.

Viewing Noise Measurements

Measurements that have been stored in the noise warning sign can be downloaded to a computer for analysis and reporting. You can connect the sign directly to a computer's USB port, over a WiFi connection or download via a USB memory stick.

When using a memory stick the SoundEar 4 will automatically transfer its measurements on to a memory stick that is plugged in. You then take the memory stick to a computer and load it into the SoundEar software.

You can also view the live sound levels by connecting the SoundEar 4 Industrial over WiFi or via the computer's USB port and running the SoundEar software.

Data Logging Settings

The SoundEar 4 Industrial stores noise measurements in its internal memory. You can configure it to store a minimal amount of information for longer, or to store everything for a shorter period of time.

The Noise Processor's internal memory is large enough for more than 18 months storage without download - although of course we would recommend regular download to avoid data loss.

Microphone Calibration

If you have a Sound Level Calibrator and need to ensure the accurate operation of the SoundEar 4 Industrial then the software deals with this. Connect the noise sign to the software, connect a microphone extension cable and fit the calibrator to the microphone. The software Microphone Calibration option will then deal with the process of checking and adjusting.

Digital Display Settings

The SoundEar software can configure the sign's digital display to show:

  • Fast Sound Level dB(A)
  • LAeq,1s (average sound level, LAeq, every second)
  • Alarm Level
  • Time
  • Nothing (the digital display will be off)

Although the default is to show the sound level, it can be useful to turn this off if it causes confusion (not everybody understands dB) or if it causes people to make noise to see how loud they are!

Trigger Settings

The software can be used to set the trigger levels and times for each of the green, yellow and red lights to come on. Much of this can be done using the keypad on the front of the sign, but it is much easier in the software.

For each light you can set:

  • Lit or Flashing
  • The levels between which it is lit/flashing

Trigger based on:

  • dB(A) Fast or dB(A) Slow
  • LAeq,1s or LCPeak
  • How long the sound should be exceeded before lighting (avoid lighting up at the slightest exceedance)
  • How long the light should stay on for
