Noise not only disturbs adults, it can cause hearing loss, ear noise, sleep disturbance, learning difficulties, and physical stress reactions in children, which seriously affects children's physical and mental health.
According to statistics, 8.8% of children aged 8 to 14 years have hearing loss on at least one ear of more than 20 decibels. In the group of children between 8 and 14 years of age, there is at least one tone intolerance, and the middle and high tones mainly reflect the frequency range of hearing impairment caused by noise. Noise not only affects hearing, but also burdens the entire body, especially environmental noise.
What causes your child's hearing impairment
Toy guns, blasting balloons, toy horns, or whistles can all produce high volume. Often these toys also produce noise that affects children's hearing. Because their sound is very short, they cannot be recorded at their full volume. But this does not mean that these sounds have less impact on children.
The volume of electro-amplified music, portable music equipment such as MP3 players, etc. all cause children's hearing impairment.
Noise levels and their impact on hearing
After excess sound, tinnitus, rustling, or dull sensations are signs of temporary hearing impairment because damaged cells in the inner ear can initially recover on their own. Human ears usually require the necessary rest period of 10 to 12 hours, and if the ears are frequently or continuously subjected to excessive sounds, it can cause chronic howling or even permanent hearing loss.
Impact of environmental noise on the entire body
For example, environmental noise from transportation, airplanes, and construction work has a greater impact on the ears and can also burden the entire organism. This disturbing noise that humans cannot escape leads to emotional anger and dissatisfaction. Studies have shown that noise makes it difficult for children to fall asleep, resulting in increased blood pressure and increased release of stress hormones. Further research found that at the airport, aircraft noise greatly reduces children's learning efficiency and affects children's academic performance.
Noise levels and their effects on the body
The unit of measurement of sound intensity related to human hearing is decibel or abbreviation:
• 55 decibels of traffic noise at night can cause sleep disturbances and harm health in the long run.
• Continuous sound exceeds 80-85 dB. Prolonged proximity to the speaker for 120-130 minutes can cause permanent hearing impairment sound pressure levels. Noise in the range of pain thresholds can cause ear damage even with short exposure times.
• Peak levels above 135 dB have caused hearing loss in individual sound events.
Tips for parents
Children and adolescents need to speak freely. Loudness is fun. Loud laughter and screaming are loves of life and happiness. The euphemistic loudness and the calm of relaxation are not opposites, but important, alternating phases.
• Let yourself and your child enjoy some "quietness" (about 30 minutes) at work or in daily life, each with its own way-wear soundproof earmuffs, draw pictures, make a puzzle, crosswords, etc. Mainly pleasant and quiet.
• Soft lighting also reduces volume: for example, candlelight at dinner can support quiet conversations.
• Often go for walks in the woods and grass. Not only does it provide exercise in the fresh air, it also protects the ears from daily noise and promotes the perception of quiet sounds in nature.
• Don't buy noisy toys. Even music boxes and squeaking animals shouldn't be so loud that children's hearing can be impaired if they hold toys on their ears.
• Avoid using toy pistols, cracks, children's horns, and other items. Equally serious and dangerous items are not strictly toys.
• When purchasing a portable music player, you can choose an active noise reduction earphone. It will always control the playback volume, adjust the volume according to the environment, and protect the ears from noise.
