Why ishearingprotection important

The primary criterion when selecting a hearing protector is that the level of noise entering the worker’s ears (the in-ear noise level) must be reduced (attenuated) to below the criteria in the exposure standard for noise (Clause 56 of the Workplace Health and Safety Regulation 2017), which are:

Personal hearing protectors must be regularly inspected and maintained to ensure they remain in good, clean condition. The inspections should check that:

"This type of surveillance undoubtedly will harm communities of color and others who are overpoliced, and likely well beyond that," the resigning board members wrote. "The Taser-equipped drone also has no realistic chance of solving the mass shooting problem Axon now is prescribing it for, only distracting society from real solutions to a tragic problem. We all feel the desperate need to do something to address our epidemic of mass shootings. But Axon’s proposal to elevate a tech-and-policing response when there are far less harmful alternatives, is not the solution."

Suppliers of hearing protectors should provide the full information on the attenuation (reduction in noise intensity) likely to be provided including the SLC80 ratings, class and octave band attenuation values. The attenuation values should be derived from attenuation measurements made in accordance with AS/NZS 1270 Acoustics – hearing protectors.

Areas where people may be exposed to hazardous noise should be sign-posted as hearing protector areas and the boundaries of these areas should be clearly defined.

For information on the SLC80 (Sound Level Conversion valid for 80% of the wearers) measuring method, refer to the Managing noise and preventing hearing loss at work Code of Practice.

The system would have tapped into security camera feeds to detect active shooter events using both human monitoring and artificial intelligence. While a human operator would have made the final decision on whether to fire a Taser, Axon planned to develop "targeting algorithms" to help them with "properly and safely aiming the device."

But it’s important to know that providing hearing PPE that over-protects a worker (ie: the hearing PPE is rated higher than the protection level determined by the workplace noise assessment) cuts out too much sound and may cause workers to experience disadvantages, such as:

Then, based on the workplace noise exposure levels and the target in-ear noise exposure level, the workplace assessment will determine what level of hearing protection will correctly reduce (attenuate) the noise intensity received in a worker’s ear.

They provide no protection at all – in fact, they actually add to the level of outside noise and contribute to damaging a person’s hearing.

Axon CEO Rick Smith suggested the drones could be deployed as a measure to prevent mass shootings. As Reuters notes, he envisioned drones being stationed in school hallways and having the ability to enter rooms through vents. The drone system, which Axon suggested might be ready as soon as 2024, would have cost schools around $1,000 per year.

The nine individuals said they were blindsided by an announcement from the company last Thursday — nine days after 19 elementary school students and two teachers were killed in a mass shooting in Uvalde, Texas — about starting development of such a drone. It had an aim of "incapacitating an active shooter in less than 60 seconds." Axon said it "asked the board to re-engage and consider issuing further guidance and feedback on this capability."

Ear protectionPPEuses

In order to get the full protection of hearing PPE workers must wear their PPE AT ALL TIMES whenever they are exposed to hazardous noise during their work shift.

Where sign-posting is not practicable, you should make other arrangements to ensure that workers and others know when personal hearing protectors are required.

Once the hearing protection level has been determined by the workplace noise assessment, you need to provide a suitable range of hearing PPE for your workers to choose from, so they can select the type that suits them best.

Those board members said that before Axon made its announcement, they urged it to "pull back" on the plans. "But the company charged ahead in a way that struck many of us as trading on the tragedy of the Uvalde and Buffalo shootings," they wrote. "Significantly for us, it bypassed Axon’s commitment to consult with the company’s own AI Ethics Board."

If the hearing PPE is removed, even for a short time, the protection provided to the worker will be substantially reduced.

You should set a target in-ear noise exposure level for your workers that is below the exposure standard for noise, eg: 80 dB(A). An in-ear noise level is the noise level received in a person’s ear when using hearing PPE.

Suppliers of hearing protectors should provide the full information on the attenuation likely to be provided including the SLC80 ratings, class and octave band attenuation values derived from attenuation measurements made in accordance with AS/NZS 1270:2002 Acoustics – hearing protectors.

To identify what class of hearing protection, you only need the 8-hour average value to which the worker is exposed in dB(A).and then refer to Table 4 in the Managing noise and preventing hearing loss at work Code of Practice, which details the five classes of hearing PPE:

The AI ethics board has had previous success in convincing Axon to change course. In 2019, the company said it wouldn't use facial recognition in its police body cameras after the board expressed concern about the plan.

Providing or using hearing PPE measured by the Noise Reduction Rating (NRR) system is not acceptable in Australia. The NRR system is used in the USA but can’t be used in Australia because the method of testing is different from that required by AS/NZS 1270:2001.

Nine of the 12 members said in a resignation letter that, just a few weeks ago, the board voted 8-4 to recommend that Axon shouldn't move forward with a pilot study for a Taser-equipped drone concept. "In that limited conception, the Taser-equipped drone was to be used only in situations in which it might avoid a police officer using a firearm, thereby potentially saving a life," the nine board members wrote. They noted Axon might decline to follow that recommendation and were working on a report regarding measures the company should have in place were it to move forward.

Personal protective equipment (PPE) – including hearing PPE – is the least effective control in the hierarchy of controls because it:

Axon has paused work on a project to build drones equipped with its Tasers. A majority of its artificial intelligence ethics board quit after the plan was announced last week.

Workers and other persons, including managers and visitors, should never enter these areas without wearing appropriate personal hearing protectors, regardless of how short the time they stay in the hearing protector area.

Personal hearing protectors should be selected and maintained in accordance with AS/NZS 1269.3:2005 Occupational noise management – hearing protector program.

Smith said that the goal of the announcement was to start a conversation about the use of drones equipped with Tasers as a possible solution. "I acknowledge that our passion for finding new solutions to stop mass shootings led us to move quickly," Smith said in a statement. "However, in light of feedback, we are pausing work on this project and refocusing to further engage with key constituencies to fully explore the best path forward."

The class of hearing protection is determined by a testing regime prescribed by AS/NZS 1270:2002 Acoustics – Hearing protectors and is marked on the packaging of the device.
