There are the following differences between noise-canceling headphones and earmuffs:
Noise-canceling principle:
Noise-canceling headphones: They mostly use active noise-canceling technology. They collect external noise through the microphone inside the headphones and generate sound waves with opposite phases to the noise after chip analysis and processing. The speakers then play these sound waves to cancel out the noise.
Earmuffs: They generally block sound physically, using soft materials and a good sealing design. They fit tightly to the head, reducing the sound from entering through the gap and effectively isolating high-frequency noise.
Noise-canceling effect:
Noise-canceling headphones greatly affect various noises, especially when suppressing low-frequency noise.
Earmuffs: They can reduce surrounding noise in general daily environments, and the technology is relatively simple to implement, which can solve most daily noise problems.

1. Industrial workers
   • Scenarios: In noisy working environments with high noise intensity, such as factory workshops, construction sites, airport ground services, etc. For example, in a machining workshop, the continuous noise generated by lathes, milling machines and other equipment can be as high as more than 85 decibels; the noise generated by pile drivers, concrete mixers and other equipment on construction sites may exceed 90 decibels.
   • Groups of people: Workers who are exposed to such environments for a long time, such as mechanical workers, construction workers, airport baggage handlers, etc., need to wear earmuffs to protect their hearing. These people may be in a high-noise environment for 8 hours or even longer every day. If they don’t take protective measures, their hearing is easily damaged.
2. Military personnel
   • Scenarios: In military training environments (such as gun shooting ranges), combat environments or around military equipment such as aircraft carriers and helicopters. When guns are fired at the shooting range, the instantaneous noise can reach about 140 – 160 decibels; the noise generated when a helicopter is flying can also be as high as more than 100 decibels.
   • Groups of people: Including army soldiers, air force ground crew, navy ship crew, etc. They will frequently be exposed to high-noise equipment and environments during the execution of tasks. Earmuffs can effectively reduce the damage of noise to their hearing and ensure their hearing health in military operations.
3. Music workers and enthusiasts
   • Scenarios: In concert venues, recording studios, band rehearsal rooms and other environments. At a rock concert, the volume may reach 110 – 120 decibels; in a recording studio, in order to achieve the ideal sound effect, the volume of the audio equipment is also relatively high.
   • Groups of people: Such as musicians, sound mixers, audio engineers and avid music lovers. They are in a high-decibel music environment for a long time. Using earmuffs can protect their hearing to a certain extent and also help them better distinguish the details of sounds in a noisy environment.
4. Sports event spectators and athletes
   • Scenarios: In race tracks, football stadiums and other sports venues. When racing cars are speeding on the track, the noise can reach 130 – 140 decibels; the shouts of the audience at a large football match may also exceed 100 decibels.
   • Groups of people: Including racing drivers, football players and on-site spectators. Athletes need to concentrate during the competition and avoid noise interference. Spectators who are exposed to high-decibel environments for a long time also need earmuffs to reduce the irritation of noise to their ears.
5. Infants and children
   • Scenarios: In festival celebrations (such as setting off fireworks), noisy amusement parks and other environments. When fireworks are set off, the noise may exceed 120 decibels; the amusement facilities in the amusement park will also generate relatively large noise during operation.
   • Groups of people: Since the hearing systems of infants and children are not fully developed and they are more sensitive to noise. In these noisy occasions, wearing earmuffs for them can prevent the noise from causing irreversible damage to their hearing.
6. People with sleep disorders
   • Scenarios: In sleep environments that are disturbed by noise, such as living near traffic arteries (roads, railways), near airports or when neighbors are doing renovations that generate noise. Traffic noise may be around 70 – 90 decibels, and renovation noise can reach more than 100 decibels.
   • Groups of people: Those who are easily awakened by noise or have high requirements for the sleep environment. Wearing noise-canceling earmuffs can effectively block external noise and help them get better sleep quality.
