This document provides training on noise awareness for workers at Muscat International Airport. It defines noise and identifies its hazards such as intensity, pitch, and duration. Prolonged exposure can lead to noise-induced hearing loss. How hearing loss occurs is explained through the process of sound waves entering and damaging the inner ear. Legislation establishes limits for worker noise exposure and control measures are mandated. Control measures discussed include equipment design, barriers, distance from noise sources, and limits on exposure time. Other measures covered are maintenance, temporary barricades, signage, hearing protection, health surveillance, and proper storage of protective equipment.

- 1. MAIN CONTRACT 3 (MC3) MUSCAT INTERNATIONAL AIRPORT Noise Awareness Training 1
- 2. Welcome Trainer Toilets Alarms Mobile phones Attendance sheets 2
- 3. Noise Definition An unwanted sound, that is loud, unpleasant, and usually undesired 3
- 4. Noise Hazards So what are the hazards? 4
- 5. Noise Hazards 5 Intensity Pitch Duration
- 6. Noise Hazards 6 Noise Induced Hearing Loss (NIHL) Acoustic Trauma Conductive hearing loss Presbyacusis Sensorineural hearing loss Mixed Balance Co-ordination
- 15. Noise Legislation 15 In the event high noise areas that exceed 85 dBA (85 dBA prorated to 08 hour work day as per Sultanate of Oman ,Ministry of Manpower, Ministerial decision No. (286/2008) are identified, control measures will be taken.
- 17. Noise Guidance 17 Generators - 105.6 dB (A) Roller Compactors - 107.1 dB (A) Grader - 98.5 dB (A) Bulldozer - 111.0 dB (A) Loader - 108.2 dB (A)
- 18. Noise Guidance 18 Generators - 105.6 dB (A) Roller Compactors - 107.1 dB (A) Grader - 98.5 dB (A) Bulldozer - 111.0 dB (A) Loader - 108.2 dB (A)
- 19. Noise Inverse Square Relationship 19 As the intensity varies inversely with the square of the distance from the source. So if the distance from the source is doubled (increased by a factor of 2), then the intensity is quartered (decreased by a factor of 4).
- 21. Noise Control Measures So what are the control measures ? 21
- 27. Remember Vibration separate topic 27 Scientific researches emphasized the fact that noise and vibration, exceeding certain intensity have negative consequences for the safety and operational characteristics of technical equipments as well as for the safety and quality of the products. In the same time, clinical researches highlighted on statistical bases the fact that noise and vibration exceeding certain limits have negative medical effects by affecting the health and working capacity of the employees.
- 28. Control Measure Temporary Barricades & Hazard Warning Signage 28
- 30. Control Measure Double Hearing Protection 30
- 31. Control Measure Manufacturer Guidance 31 A-weighted noise level (dB) Select a protector with an SNR of 85-90 20 or less 90-95 20-30 95-100 25-35 100-105 30 or more
- 40. Bad Practices common equipments noise is forgotten 40

- 46. Health Surveillance Audiometric Testing for Piling workers Quarterly basis 46 Good Practices
- 48. Noise Summary of Noise Control Measures Barriers Distance Time (decrease) Barricades & Signage PPE Health Surveillance Storage (hygiene) 48
Editor's Notes
- #7: Conductive hearing loss occurs when there is a problem conducting sound waves anywhere along the route through the outer ear tympanic membrane (eardrum), or middle ear (ossicles). Presbycusis or age-related hearing loss, is the cumulative effect of aging on hearing. Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the vestibulocochlear nerve (cranial nerve VIII), the inner ear, or central processing centers of the brain
