Everyday sounds from hairdryers to concerts pose growing risk to hearing health

Noise exposure is increasingly recognised as a significant contributor to hearing loss, impacting around 5% of the global population. The World Health Organization (WHO) has documented that prolonged exposure to sounds at or above 85 decibels (dB) can result in permanent hearing impairment, while brief bursts of noise at 120 dB or higher can cause immediate damage. Understanding these noise levels is crucial for awareness and prevention.

To contextualise this risk, it is important to consider familiar sounds and their corresponding decibel levels. For instance, a typical hairdryer emits sound within the range of 60 to 95 dB. Those who use hairdryers regularly should maintain a safe distance from their ears, ideally keeping the device at least a foot away. Modern hairdryers often feature quieter designs, prompting sound-conscious consumers to consider upgrades.

Blenders, which range from 80 to 90 dB, are also common household appliances, yet users seldom experience hearing damage since they generally do not operate them at close range. A practical tip is to use a towel or a sound-dampening cover while blending to reduce noise exposure further.

Conversely, squeaky dog toys can reach an astonishing 110 dB when pressed closely to the ear. This highlights the importance of mindful play—holding the toy at waist height can prevent unnecessary risk.

Air conditioning units are typically quieter, measuring between 60 and 75 dB. However, when combined with other noise sources, such as fans or televisions, the overall sound level can rise to more discomforting, if not hazardous, levels.

The danger escalates with the use of louder tools and equipment. Leaf blowers, for example, can measure as high as 110 dB, necessitating protective earmuffs during operation to safeguard against immediate auditory damage. Similarly, electric drills can reach 95 dB. If undertaking DIY tasks, the use of earplugs or noise-cancelling earmuffs is strongly recommended.

High decibel levels are not limited to home use. Concerts, known for their electrifying atmosphere, can produce sounds that soar to 120 dB or more. The volume experienced can vary widely based on seating position and the performance setting; a quieter experience might be found away from speaker systems, while being too close to percussion can lead to significant sound exposure.

Experts, including those from organisations such as the American Academy of Family Physicians and the National Institute on Deafness and Other Communication Disorders, stress the importance of protective measures in environments with elevated noise levels. They advocate for the use of ear protection in circumstances of sustained high noise, especially where machinery or amplified music is involved.

For anyone unsure about noise levels in their daily life, smartphone applications that measure decibel levels can provide helpful insights, enabling individuals to gauge their exposure accurately. Additionally, individuals are encouraged to consult hearing specialists if they suspect any deterioration in their hearing.

With the awareness of hazardous decibel levels and the risks associated with them, there is a compelling case for promoting safe listening habits. Protecting auditory health not only preserves quality of life but also ensures the enjoyment of sound for generations to come.
