Regulations stipulate daily personal noise exposure levels beyond which hearing protection should be used (Health and Safety Executive, HSE, 2005). If daily noise exposure is above the first action level of 80 dB(A) but below the second action level of 85 dB(A), hearing protection should be available to the employee. If daily noise exposure is beyond the second action level, or if any peak levels exceed 137 dB SPL then hearing protection must be used. Daily personal noise exposure level can be calculated from the knowledge of the level and duration of the stimuli.
VRA applies to the hearing test of infants that range from seven months - 2.5 years ago. Through the VRA test, make the child set up a conditioned reflex of stimulation sound, and attract children to turn to flash toys that reward at the same time. Use directional reflection, to motivate children can to continue to head in the direction of the sound source even stimulus itself is no longer interesting.
VAR completes the test through the stimulation of children. In the condition of the sound field, after giving sound, the children can reflex to look for the sound source, at this moment, it will start visual reinforcement signal to reward. It is suitable for 6 months to 3 years old children. Through VAR, children are more likely to cooperate and have a more accurate reaction, a hearing threshold value that is measured would be closer to the true level.
