How to choose a pair of headphones suitable for security protection and hearing?
When choosing headphones suitable for security work to protect hearing, the following factors should be comprehensively considered:
Headphone type:
Over-ear headphones: Recommended. They cover the ears to block out external noise and the sound from the headphones is farther from the eardrum, causing less stimulation to the cochlea. They can protect hearing to a certain extent. Moreover, they have good sealing properties, reducing environmental noise interference, and there is no need to increase the volume excessively.
In-ear headphones: Generally not recommended. They create a sealed space in the ear canal, which can cause inflammation of the ear canal. The sound is more concentrated on the eardrum, causing greater stimulation to the cochlear hair cells. However, if you can choose a model with a silicone sleeve that fits the ear canal well, it can reduce sound leakage and avoid the need to increase the volume due to leakage.
Noise-cancelling headphones: Very suitable for noisy security work environments. They are divided into active noise cancellation and passive noise cancellation. Active noise cancellation works by generating counter sound waves to cancel out noise and is effective for low and mid-frequency noise. Passive noise cancellation relies on physical design to block out external noise and can reduce high-frequency noise interference. Noise-cancelling headphones allow users to hear clearly at lower volumes, reducing the risk of hearing damage. When choosing, pay attention to the noise cancellation depth; the higher the value, the better the noise cancellation effect.
Bone conduction headphones: Have certain advantages. They transmit sound through the skull, allowing the ears to still receive external sounds. They are suitable for security personnel working outdoors and can prevent accidents caused by not hearing external warning sounds. They are also suitable for those with middle ear or ear canal infections. However, they still stimulate the cochlea and are not completely risk-free for hearing damage.
Sound quality and volume control:
Avoid choosing low-quality headphones as they may have issues such as unbalanced volume and noise, which can prompt users to frequently increase the volume and damage their hearing.
Some headphones have volume control functions. For example, the 1MORE HQ20 is equipped with a three-level intelligent volume control function that can effectively control the maximum volume and also has a hearing protection mode that automatically adjusts the volume and listening time. Headphones with good volume control functions are more conducive to protecting hearing.
Comfort of wearing:
Security work may require wearing headphones for long periods, so comfort is important. Pay attention to factors such as the weight of the headphones, the material and size of the ear cups, and the adjustability of the headband. For example, the 1MORE HQ20 adopts an ergonomic design, with soft sponge-filled ear cups and an adjustable headband, ensuring stable wearing without causing excessive pressure on the ears even after long periods of use.
Other factors:
Brand and reputation: Choosing headphones from well-known brands is usually more reliable. They generally have more advanced technology and strict quality control standards, providing better noise cancellation and sound quality. You can refer to relevant reviews and user feedback to understand the actual performance and user experience of the headphones.
Bluetooth version and battery life (for wireless headphones): The higher the Bluetooth version, the better the connection stability and transmission speed. A longer battery life can meet the long-term usage needs of security work and avoid frequent charging disruptions.
