Tips to Counteract the Effects of LRADs
Noise-Canceling Headphones
Noise-canceling headphones can help reduce the impact of handheld long-range acoustic devices (LRADs) by blocking out harmful sound frequencies. By wearing noise-canceling headphones, individuals can protect their ears from potential damage caused by high-decibel LRAD sounds. These headphones work by using built-in microphones to pick up ambient noise and then producing sound waves that are 180 degrees out of phase with the unwanted noise, effectively canceling it out.
Wearing noise-canceling headphones is a practical solution for minimizing exposure to harmful LRAD sounds in various settings such as protests or events where these devices might be used. Brands like Bose and Sony offer a wide range of noise-canceling headphone options that cater to different budgets and preferences. Earmuffs designed for shooting ranges or construction sites can also serve as effective alternatives for reducing the impact of loud noises on individuals' hearing.
Seek Distance
Maintaining a safe distance from handheld LRADs is crucial in mitigating their effects on individuals' health. The intensity of sound produced by these devices diminishes as distance increases, reducing the risk of auditory damage significantly. When encountering an LRAD deployment, moving away from its direct line-of-sight and seeking shelter behind barriers or structures can provide added protection against its harmful effects.
Keeping a safe distance from LRADs not only helps minimize immediate risks but also prevents potential long-term hearing issues associated with prolonged exposure to high-intensity sound waves. In situations where avoiding proximity to an active device is challenging, utilizing natural barriers like trees or buildings can act as effective shields against excessive noise levels emitted by handheld LRADs.
