LABELO measures sound pressure levels for the qualification of environments to carry out audiometric tests by air and bone conduction. The work is based on both international standards and Brazilian project norms.
Project 03-029.01.027/1 Methods for the assessment of environments for audiometric tests – Part 1: Direct Measurement.
Project 03:029.01-025/1 Methods for conducting audiometric tests Part 1: Pure tone audiometry by air and bone conduction.
The standards used are an international benchmark, type 1 octave-band analyzers to measure sound pressure level (equivalent sound pressure level – Leq), analysis on octave bands or one-third octave bands. Sound level calibrator, also class 1. In accordance with the relevant standard for instrumentation.
All equipment is calibrated at LABELO/PUCRS facilities, which include an electroacoustics laboratory accredited by RBC or Cgcre.
