Answer 22

BS 4142 is a British Standard document that provides guidelines for
assessing and managing the industrial and commercial noise impact
on surrounding areas.

Question 23

what are some places / areas that BS4142 would be used

Answer 23

sound from industrial and manufacturing processes

sound from fixed installations which comprise
mechanical and electrical plant and equipment

sound from the loading and unloading of goods and
materials at industrial and/or commercial premises

Question 24

what is a noise rating curve

Answer 24

These are a series of curves derived from an octave band frequency
analysis to assess the acceptability of noise from fixed plant or
machinery

Question 25

What are some benefits to using noise rating curves

Answer 25

They help determine and describe the loudness of different sounds, like those from machinery across different
Providing comparable ratings of loudness for various noise sources, simplifying the communication of noise
Used to establish noise regulations and guidelines, enabling authorities to control and limit noise pollution in
Engineers and manufacturers use these curves to design quieter products and equipment.

Question 26

Will noise rating curves be used in planning conditions

Answer 26

YES

Question 27

Why is it important to monitor workplace noise

Answer 27

Noise at work can cause hearing damage that is permanent and disabling

Noise at work can interfere with communications and make
warnings harder to hear. It can also reduce people’s awareness of their surroundings. These
issues can lead to safety risks – putting people at risk of injury or death
