HearingprotectionPPEdefinition

There are three main types of hearing protective devises that help reduce the risk of ear harm in a farm operation: Foam ear plugs, earmuffs, and semi-aural devices (also called canal caps).

That said, finding the battery when it's time to change it out might have some gamers scratching their heads. The engineers who designed the Oculus controllers wanted them to feel smooth and seamless, so there isn't an obvious clasp or anything like that to indicate where the user needs to open it up when it comes time to change out the battery. The process is pretty simple when you know how though.

HearingprotectionPPEstandards

Personal Protective Equipment (PPE) is vital to maintain the health of swine farm workers who are continuously exposed to loud noises. It is the farm ownership’s responsibility to provide PPE to these farm workers, and to ensure that all people on the farm are effectively trained in PPE use and compliance. The objective of this article is to identify the tasks on the farm that require hearing protective devices, and to describe the kinds of PPE available for swine farm workers.

Why ishearingprotection important

There have been several iterations of the Oculus, (now Meta) controller, and most of them run on AA batteries. This might seem like a primitive power source in this day in age, but it's designed that way for the user's convenience. Rechargeable controllers with built-in batteries are great for most consoles since you can simply play with them plugged in when they run out of juice. But tethering VR controllers to a power outlet can cause all sorts of problems.

According to the Occupational Safety and Health Administration (OSHA), noise exposure is detrimental to hearing health when exceeding 85 decibels (dB) for long periods. Several tasks on the swine farm exceed this OSHA-defined threshold, including heat checking, piglet processing, snout snaring, power washing, and feed milling (Humann et al., 2005; Achutan and Tubbs, 2007). Workers who regularly engage in these tasks would benefit from farm participation in a Hearing Conservation Program (as defined by OSHA Standard 1910.95). The Hearing Conservation Program encompasses workplace and worker monitoring, and farm provision of regular audiometric testing, hearing protection, and training materials to workers at no cost.

Using AAs allows the gamer to choose between disposable and rechargeable options while also freeing them up to swap out dead batteries in an instant rather than having a game session ruined when one of the controllers goes dead in the middle of a round of "Beat Saber." It's also one of the many ways that Meta keeps production costs low which has allowed the Quest 2 to remain one of the cheaper performance VR headsets on the market even after its unwelcome price hike in 2022.

The best hearing protection is obtained by wearing earplugs and earmuffs together. It generally takes 10 days to get used to hearing protection, just as it takes a while to get used to a pair of new shoes. Improperly worn hearing protection devices may not reduce noise levels. Hearing aids are NOT hearing protectors. Persons with normal hearing always can detect some sound while wearing hearing protection devices.

Ear protectionPPEuses

When hearing protective devices are properly fitted, the sound of your own voice should change, becoming deeper, hollow, or muffled. If you don’t hear the change, or if it isn’t the same in both ears, you haven’t obtained a proper fit and acoustic seal in either one or both ears.

Once the new battery has been inserted, all that's left to do is replace the magnetic panel and then repeat the process on the other controller. They should automatically re-synch with the Oculus client app once you press any button to turn each of them back on. Then you should be all set to dive back into your virtual world.

If you look closely at one of the Oculus controllers, you should see a seam separating the plastic panels on the grip. One of these panels is permanently fixed to the controller while the other is magnetically held in place. Place your thumb at the top of the panel opposite the triggers, just below the face where most of the buttons are located. Now apply pressure toward the bottom of the controller to break the magnetic hold and slide the panel out of place. You should now be able to see the battery inside.

Several tasks on the swine farm produce noises at volumes that can be detrimental to human hearing. It is the farm’s responsibility to provide hearing protective devices to farm workers to maintain their hearing health. Further, it is the farm’s responsibility to ensure that all farm workers are trained to use hearing devices correctly. The best hearing protection comes from using earplugs and earmuffs together, yet hearing protection is a personal choice and is influenced by noise level, comfort, and the compatibility for both the worker and the environment. Accordingly, the best hearing protective device is the one that farm workers use consistently and correctly. To that end, offering multiple hearing PPE choices to farm workers provides the best protection of hearing health.

Remove the battery and replace it with a new AA, making sure that the positive side of the new battery is facing the bottom of the controller. If you haven't already, this is a good opportunity to swap out any disposable batteries for some quality rechargeable ones. In addition to being more environmentally friendly, they're also much more cost-effective in the long run.
