The hair dryer is an indispensable tool for hairdressers and hair stylists. The data shows that multiple hair dryers can be used at the same time, and the noise can often reach 85 decibels. Research shows that if exposed to such a large noise environment, 8 hours are more likely to appear progressive. Sexual hearing loss.
Kindergarten teachers are a group of lovely children because of their working environment. Sometimes they often make all kinds of noisy sounds, and the noise can often reach 85dB. In order to prevent hearing loss, it is hoped that the kindergarten teachers can conduct a hearing test every year.
Orchestra / music lovers
Musicians who often rehearse and perform may suffer from noise-induced hearing loss due to the long-term exposure to 85dB~105dB. Another study showed that 139 people in 59 orchestras had higher hearing loss than their age. Need to care for hearing health!
Miner / Construction Worker / Carpenter / Manufacturing
Due to the need to use electric tools or mechanical work in the work, it is easy to be in a loud noise environment. When mining ore, the noise level can be as high as 135 decibels; if hammered, it will produce up to 130 decibels. According to research, workers are exposed to 70 decibels or higher at close to 85% working hours, but their hearing protectors are less than 20%. Therefore, such occupations must regularly check hearing and do routine noise protection. Construction equipment units should provide workers with protection machines above 90 decibels.
Audio staff or nightclub staff
This ambient noise level is usually higher than 115 decibels. It is difficult to hear clearly. However, most nightclub staff such as bartenders, guards, and DJs work in such an environment for a long time, which can easily lead to hearing loss. Therefore, it is necessary. Noise protection equipment and regular hearing checks are necessary.
Drivers in the cockpit of F1 cars may produce up to 135dB of sound, so for the racer’s profession, ear protection must be done to reduce the risk of hearing loss.
Streets, parks, etc., which are neatly arranged and beautifully decorated with flowers and trees, are all derived from the heavy noises of gardeners holding lawn mowers. You can know that these machines can produce up to 107 decibels when they are working properly. The noise, therefore, they also need to use anti-noise earplugs or hood-type noise-proof equipment.
Bus driver and passenger
Bus drivers are often in a noisy traffic environment during daily commutes, passengers hum, and loud commuter music nearby. They have to face more than just traffic jams in their careers, as well as headaches and earaches. In addition, passengers are also at risk: in order to reduce the surrounding noise, such as the voice of other passengers around and the background noise on the bus or train, some passengers will increase the volume of the speech to 100db, which may cause damage to the tympanic membrane and The risk of the inner ear.
Airport ground crew/air traffic controller
They endure the huge noise generated by the take-off and landing of the aircraft every day. Data measurements show that the amount of noise from landing and take-off of the aircraft can be tested up to 140dB. To engage in such a profession, you must do noise protection and check your hearing regularly!
Firefighter/ambulance pilot/force officer
Many studies have shown the incidence of hearing disability in firefighters and emergency vehicle drivers, and most have found that firefighters have increased hearing loss compared to the general population of the same age. Forces in the actual practice of gunshots, explosions, aircraft engines, etc., a large number of equipment and weapons can reach 140dB, which can only greatly damage the hearing.
Motor vehicle driver
In most motor vehicles, such as trucks, cars, and truck drivers, the noise and wind noise generated by motor vehicles can cause hearing damage, and as the driving age increases, the degree of hearing loss will gradually increase. The influence of wind noise is often obvious for the driver, and the hearing loss of the left ear is obvious, and it is also different due to different driving positions in different countries. Therefore, for motor vehicle drivers, it is necessary to perform regular hearing tests, equipped with hearing protection devices such as anti-noise earplugs or earmuffs, to reduce the risk of hearing loss.
A report published in the Environmental and Occupational Medicine indicates that high-frequency turbines (dental-specific mobile phones) used by dentists emit high-frequency sounds (average 6KHz) that cause dentists to be exposed to 4KHz-6KHz (average intensity 70-77 decibels) There is a phenomenon in which the threshold is increased in the noise. Moreover, the right-handed dentist has significant hearing loss in his left ear. When the dentist uses a dental handpiece above 20 cm, the noise is below 80 decibels. When the distance is 10 cm, the noise generated by the high-speed turbine (dental-dedicated mobile phone) and ultrasonic cleaning is greater than 85 decibels. Therefore, the dentist needs regular hearing tests.
If your occupation is mentioned in the above, you must pay attention to hearing health, regularly test your hearing, and do a good job in preventing hearing.
