A sound level meter is used to measure sound pressure levels in decibels (dB). The device is often tripod-mounted and used in a fixed location.

Measuring sound levels for the purpose of determining occupational noise exposure must take into account a “time-weighted average noise level of 85 dBA or higher over an 8-hour work shift.” Consult your safety manager or an environmental safety and health professional for assistance with compliance and noise exposure mitigation. Resources are available from OSHA and industry groups.

Three factors combine to determine whether you’re at risk for hearing damage from noise exposure: sound level, time and distance. Sounds above 85 decibels are risky and sounds above 125 decibels will cause immediate hearing damage. The risks increase with the amount of time you’re exposed to loud noise, and how close you are to the source of that noise. The louder it is, the longer you’re exposed and the closer you are to it, the more you’re at risk for hearing damage.

The Occupational Safety and Health Administration (OSHA) requires employers to take steps to reduce occupational noise exposure when an employee is exposed to a “time-weighted average noise level of 85 dBA or higher over an 8-hour work shift.”

The Environmental Protection Agency requires any hearing protector sold in the U.S. to have a noise reduction rating (NRR). NRR is a measure of a hearing protection device’s ability to reduce the wearer’s sound exposure. The higher the number, the greater the potential for noise reduction.

Sonetics headsets have a Noise Reduction Rating of 24 decibels (24dB NRR).

It’s the component in a Sonetics Wireless Communication System that connects wireless headsets together. The SON150 Base Station can connect up to five wireless headsets.

The ComHub stores the wireless base station in a portable, battery-operated, weatherproof case. As such, you can pick up the ComHub and carry it around the work zone with you. You also use the ComHub to connect a two-way radio.

You can expect up to 24 hours of battery life from the SCH305 ComHub, and up to 12 hours from the SCH310 and SCH310T ComHubs.

A status LED next to the power button flashes from 1 to 4 times when the ComHub is powered on. Four flashes indicates a full charge. A single flash means it’s time to charge the ComHub.

Use the provided 12VDC regulated wall adapter or the ComHub charging cable in your Sonetics Charging Case.

Make sure you position the ComHub upright (there are stickers on the case to help you orient it). Raise it up off the ground as much as is safe, and try to have as few obstacles between the ComHub and the headsets as possible (clear line of sight).

You can connect virtually any make/model of portable two-way radio.

Watch this quick video on how to connect a portable two-way radio to the ComHub, or review the full instructions in your ComHub user manual.

You can select up to five channels available on the Base Station and switch between them with a button on the headset. The factory default is a single channel.

For tethering to work with a SCH305-BT, the ComHub needs to be set up into Channel Mode: Set up for 2 Channels. This is not needed when you are only using the SCH305 ComHub version. Reason for this, is the addition of the Bluetooth module in the SCH305-BT. You can tether with the SCH305-BT ComHub, but you cannot access the device which is Bluetooth paired to the SCH305-BT from the same channel as the tethered group. The tethered group will be on Channel 2 and the Bluetooth paired device is on Channel 1.

Most teams that communicate with Sonetics wireless headsets rarely need the system’s full range. When team members are within a few hundred feet of a ComHub on a Vactor or tow truck, crane, construction job site or factory floor, DECT7 connectivity is strong and dependable. But some teams need every inch of the 1,600-foot range that DECT7 provides from a ComHub. Road construction crews, agricultural workers and marine operations often include team members who need to work at the edge of DECT7’s range, where they can still take advantage of interference-free, secure communication that’s as clear and seamless as a landline conference call. Remember these three phrases when you want to extend the range of your Sonetics wireless team communication system: Line-of-sight Height Orientation Essential Components of Maximum Range No card tricks here. Antennas define the coverage area of DECT7 wireless. Our dual-dome antenna design in the headsets uses diversity switching to lock in the best of the two signals. In other words, users don’t need to worry about head position relative to the ComHub. No matter which way you turn, DECT7 delivers the best possible connection at all times. Speaking of the ComHub, it’s the central nervous system of your work site’s wireless communication setup. As long as you have a charged ComHub and headsets, you have a secure, local communication network no matter how remote your jobsite. There are no external antennas that break, snag or need to be replaced. Everything is contained in a weatherproof portable case. Official specifications for the range of DECT7 wireless from a ComHub is 1,600 feet line of sight. Where you position your ComHub factors greatly into achieving that maximum range. Outta Sight, Outta Touch? The first guiding principle to help you maximize range, “line-of-sight,” doesn’t necessarily mean that you have to be able to see the ComHub from just over five football fields away. This is not an eye test. But as long as there are no barriers between you and the ComHub, you can expect uninterrupted communication at up to 1,600 feet. Barriers can reduce the system’s range as your signal uses some of its power to climb over and around structures and equipment. So if the ComHub is blocked from your line of sight by a lot of big, heavy equipment, walls or mountains, then you will have to use trial and error to determine the best placement. To help you position the ComHub, the headsets include an out-of-range voice prompt if the connection weakens and is about to be lost. Range testing the Sonetics ComHub. The Height of Elevation Getting the ComHub off the ground is actually an extension of the line-of-sight guiding principle. You’ll have a better chance of seeing the ComHub from five football fields away if you raise it up in the air. Usually, the range will be greater if the ComHub is four to 16 feet off of the ground. This is also the best way to avoid ground-level obstructions such as automobiles, boulders, or small trees. The ComHub is housed in a sturdy, weatherproof nylon bag with a coated hook attachment, so it’s easy to securely hang off of a ladder or aerial lift. Stand Up for Orientation Orientation matters: Vertical and horizontal orientations deliver the most consistent results. How you orient the ComHub also matters. Of the three standard options for orientation—vertical, horizontal or flat—vertical and horizontal both help you maximize the system’s range. Beyond 1,600 feet For all team members to take advantage of full-duplex or broadcast connections in crystal-clear DECT7, they need to be within range of the ComHub. It is possible in some circumstances to extend range beyond 1,600 feet (for example, we got 4,400 feet of range using the idealized setup shown in the photo above). However, you should have backup communications at the ready if you know you’ll be operating at the edge of DECT7 range. Beyond DECT7 range, the entire world is within reach. You can direct-wire a connection to a two-way radio if you want to extend the range to a few miles. Note that you’ll be subject to the two-way limitations of PTT and half-duplex communication. Bluetooth-enabled systems also allow you to wirelessly connect to your cell phone with your headset, giving you global communication options.
