High Quality Sound Blocking Headphones for Adults

The choice of hearing protection can be made effectively by choosing sound blocking headphones for adults, which conform to the ANSI S-3.19 and CE-EN-352.1 standards. The testers may encounter many practical problems while evaluating the design and functional parameters of these devices. Once of them is the applicability issue. This can be illustrated with a practical example. The laboratory and real time tests can be conducted by choosing users randomly based on their working environments, head sizes, age, existing health conditions and other finite number of parameters.

The products get certified and they are released to the market. When users in completely different set of conditions for the same set of parameters (or untested parameters) are exposed to the devices, they may experience some issues which are yet to be resolved.  The applicability of the devices may be put under elements of doubt.

Research on Sound Blocking Headphones for Adults

The ANSI S-3.19 and CE-EN-352.1 standards keep evolving with time to include all the possible real time conditions to which the sound blocking headphones for adults may get exposed.

  • Attenuation values are measured under varying frequencies of noise. For example the standard tests expose the devices to 64HZ-800HZ frequency values. The duration of exposure may last from 8 hours to more than 72 hours at a stretch. Since it may not be possible to use one person as user for this type of hard testing, many of the certifying bodies use simulated conditions. They help in practical evaluation of the devices, while keeping the users under maximum comfort levels. The number of tests and their results are subject to continued analysis within specific time span to assess the reliability factors.
  • Noise Reduction Rate of the devices is evaluated under continuous exposure to high frequency noise waves. Same tests are repeated for impulsive noise generated by gunshots. The attenuation value when exposed to the muzzle blast waves is measured within the span of 3 to milliseconds. Recommendations are made for improvement when the deviations are more than the tolerance limits allowed by the quality standards. Re-tests are conducted after the corrective and preventive measures are performed by the designers and manufacturers of sound blocking headphones for adults.
  • The real research is about reducing the time required for change implementations for improving the design and functional parameters of the protective devices during the testing and certification phases. Moreover there needs to be vast improvements in testing them on users under real time conditions. This includes an increase in the range and type of users within specific time. When this has to be done at the global levels, the required effort is naturally more. Designers and manufacturers who are able to conduct maximum possible tests under real time conditions can expect to fine tune their products to the needs of global market.
  • Makers of ClearArmor 141001 Shooters Hearing Protection Safety Ear Muffs have been able to meet all the real time challenges in developing the right kind of sound blocking headphones for adults.
