Protectores auditivos is a free Android utility app developed by INSST. The app calculates the noise attenuation provided by an ear protector with medium-high accuracy. It uses the values H, M, L that usually appear in the manufacturer's brochure and the global weighted noise levels A and C obtained from ambient noise measurement. The app also calculates the actual attenuation of the ear protector considering its usage time. If the ear protector is not used for the entire exposure time, the theoretically offered attenuation (manufacturer's information, obtained in laboratory tests) may be significantly reduced. The app is an essential tool for professionals working in high noise level environments, such as construction sites, airports, and factories.

The Protectores auditivos app provides a simple and user-friendly interface. The app is easy to use and does not require any special technical knowledge. The app is accurate and reliable in its calculations, making it a valuable tool for professionals. Protectores auditivos is an essential app for anyone who needs to calculate the noise reduction offered by ear protectors.
