Otoplastic hearing protection is custom-made and is individually fitted to the wearer’s ear. Therefore, it is more comfortably worn than standard hearing protection and offers more reliable attenuation effects without over-attenuation. Further advantages are:

Outstanding comfort

• No unpleasant pressure in the ear resp. around the head even when wearing long-term.
• No perspiration  
• Free mobility of the head
• Easy to insert and to remove

Attenuation performance

• Precise attenuation performance without acoustic isolation
• Clear environmental and danger perception  
• No limits for persons wearing glasses
• Outstanding compatibility with other protective equipment

Depending on the fitting of a hearing protection, there are two models of ear moulds: Plain-concha otoplastic is worn in the outer ear, whereas the canal otoplastic is worn in the ear canal:

Plain concha otoplastic Defined, safe fit in the ear Visible from the outside (control of the wearing quota)

Ear canal otoplastic Less visible (e.g. for musiciens/artists) Deeper in the ear (e.g. as a protection for sleep) Sensitive on jaw movement

Traditionally, otoplastic hearing protection is manufactured in acrylic or silicone whereas new digital manufacturing processes use nylon. Depending on the used material, the otoplastic is hard or soft:

Hard: acrylic or nylon Long life, long product life cycle No discoloration or embrittlement Safe fit of filter and cord Easy to insert and to remove Nylon: outstanding comfort without itching or sticking Nylon: excellent heat dissipation from the ear (hollow mould)

Soft: silicone or PVC more likely to ‚accept’ an incorrect dimension often preferred for ear canal otoplastics (see above)
