Autism Earmuffs are objects designed to cover a person’s ears for hearing protection or for warmth. They consist of a thermoplastic or metal head-band, that fits over the top or back of the head, and a cushion or cup at each end, to cover the external ears.
Modern earmuffs come in two basic kinds:
- Thermal earmuffs, worn in cold environments to keep a person’s ears warm with pads of cloth or fur.
- Acoustic earmuffs, also known as ear defenders: cups lined with sound-deadening material, like thermal earmuffs and headphones in appearance, which are worn as hearing protection. These may be carried on a head-band or clipped onto the sides of a hard hat, for use on construction sites. Some manufacturers combine headphones with ear defenders, allowing the wearer to listen to music, communication or other audio source and also enjoy protection or isolation from ambient noise. For extra sound attenuation, earplugs can also be used in conjunction with earmuffs.
Ear defenders protect the wearer from extreme noises. The head-band and outer covering is usually made from a hard thermoplastic or metal. The protection usually comes from acoustic foam – this absorbs sound waves by increasing air resistance, thus reducing the amplitude of the waves. The energy is transformed into heat.
Earmuffs can be used in the workplace or recreationally for loud activities, e.g., concerts, shooting firearms, heavy machinery, mowing, etc.
In this day and age when everybody who feels “has made it” and has a few properties to keep secure, a licensed gun purchase is the next thing that comes to mind.

Exposure to high level noise (190 dB SPL) may cause the earmuff to vibrate off the external ear causing a leak which would allow hazardous exposure to dangerous levels of noise. In loud enough environments, the ear canal can vibrate, causing the air trapped inside the ear cup to vibrate as well. This typically only occurs with low frequency noise, but can reduce the effectiveness of the hearing protection device. Technology in earmuffs is developing and shows promise in reducing the effects of airflow vibrations in the ear muffs.
