A practical tool for hearing protection.
HPD Calc is available now, free to workers, while the commercial platform is developed.
The Audiometrics Canada HPD calculator provides screening estimates for the protected noise level at the ear. It supports earplugs, earmuffs, and dual protection, with occupation references or measured exposure input.
Users can search for a product or enter its Noise Reduction Rating manually, select their jurisdiction, and view the calculation breakdown and a printable summary.
A screening estimate, with context
Occupation references describe published typical or measured exposures; they do not establish conditions at a particular workplace. Actual protection also depends on fit and use. The calculator does not replace calibrated measurement, a formal noise assessment, or a hearing conservation program.
HPD Calc remains a free worker-facing tool. It does not require a subscription to the planned Field and Office product.
