Metal detectable dB Blocker™ Benefits


Most hearing damage arises when an ear plug is removed for conversation and comfort. Metal Detectable dB Blockers™ are made to fit the individual’s ear exactly and stay in place without pressuring the ear so comfort is not an issue. This gives the worker a product that provides effective hearing protection and stays in the ear all day long.


Metal Detectable dB Blockers™ contain a proprietary frequency-tuned filter that enhances interpersonal communication. In fact, people can communicate in noise better while wearing their dB Blockers™ than if they were to remove them; they can also be integrated with radio communication devices. Whether you’re using a radio or talking interpersonally, the dB Blocker™ will stay in one place – the ear. If radio communication is needed, an additional vent is required in the protector to be used for radio connectivity.


With a comfortable fit and the ability to communicate with a B Blocker in place, workers will comply with the Hearing Loss Prevention Program. As well, Metal Detectable dB Blocker™ ear pieces are permanently attached to the lanyard. Both protectors and the lanyard are detectable should they break or fall into the process. Cold temperatures will not make them brittle, and they are  also heat resistant. These features provide workers with an efficient hearing protection device suitable for all food and pharmaceutical manufacturers and processors.


dB Blockers™  are much less expensive to use than disposable earplugs or muffs. You can save up to 60% over 5 years on a program when an entire facility is fit. The cost per month for dB Blockers™ is lower because you can wear them for 5 years. Ask us to show you how dB Blockers™ can be a cost effective solution for your hearing protection needs.
