Series(s) mHsec app(s) that 3R Brazil Environmental Technology developed to meet you with applications cost affordable, simple, clear and efficient in the area of health and safety (HSE), generating analysis tools and support environmental measurements. It was designed by M.Sc Engineer Rogério Dias Regazzi, chosen and supported by Inova talent´s program from CNPQ / IEL Rio de Janeiro, adding technology, business and professional as Rhuan Barreto developer of this app.

The APP NoiseAdVisor TWA / Lavg is extremely easy to use and to access to get reports for personal exposed reliably to noise daily or weekly. It is based on national and international criteria, as parameters of the standards chosen results: Lex, Lep, d, the Lex40, TWA8 (twax) Twa40 the Lavg, NE and the NEN, contemplating the most used functions with technical evaluation and support for assess occupational noise risk agent. You can choose the parameters as the duplicity factor (exchange rate) q = 3 or q = 5, the level criterion, the integration limit (threshold) and the fixed criteria hours 8h related to daily exposure or 40h for weekly exposure to normalize an average daily exposure for any situation. You will have the report for the daily exposure.

This application has as innovative feature its diagramming, simple data entry and quick process with the possibility to comply with any regulation, normative standard or law. Just by changing the parameters in the configuration of the APP you can compare the input data with different criteria as NR-15, NHO-1, NIOSH, OSHA. The APP is in compliance to the European Directive, ISO 1999 and ISO 9612, so it is an important tool for evaluation and measurement data, audits reports, attend the legal inspection, to help experts and professionals who work with consultancy in the area. The NoiseAdvisor TWA also allows changing quickly the language and also chosen from daily exposure (8h) or weekly (40h), converting the entries in sequence of days of the week. All results are easily exported by email with the used settings, inputs data and results.

Due to its simplicity, it can be used to evaluate exposure to high levels of sound and noise. The automatically report identifies the degree of exposure situation from a previous configuration of the APP. In the SPL entries you can enter the sound pressure level of the environment or the normalized level of previous exhibitions with the only difference being the threshold Limits, in this config. APP in case you decide to input the instantaneous sound level or short time equivalent sound level (LEQ). This is due to that the levels normalized threshold (in TWA) was previously considered and should not be applied twice. By knowing about the excesses of daily or weekly exposure this app will help people to control exposure and avoid hearing impairment.
