Frequently Asked Questions

Q. Do you have any instructions for my Ear Moulds?

Yes, please click here to view the instructions as a PDF file.

Q. As a motorcyclists which ear plugs should I have?

It does all depend upon the type of motoring you do and your preference to whether you wish to hear speech. Non filtered ear plugs cut out more sound but filtered allow speech to be heard. You may need to hear speech though your helmet that has an intercom or just when visiting a garage to refuel but not wanting to remove the ear plugs. When we see you for impression taking we will always go through your requirements to help you make the best choice for your needs.

Q. What range of colours do you have available for certain earplugs?

The following colour options are available for the above Standard Solid Silicone Noise Plugs:

Clear, pink, red, blue, beige, white, black, yellow, green, purple, orange.

We also have red, bright pink, yellow, green and orange available in neon. Gold and silver sparkles can be added to any colour or on their own in clear ear plugs. Newly added are swirl colours, a mixture of two or three colours! The choice is yours.

Q. What payment methods can I use?

Cash – Sterling (not by post)
Cheque (allow 5 working days for cheque clearance before order is processed)
Credit Card

Q. Will the ear plugs damage my ears?

Physically no, and certainly not custom made ear plugs if correctly positioned in the ears (see our instruction sheet for guidance in putting in the ears). However, if you wear standard ear pieces attached to MP3 players or ipods, excessive high volume over long periods of time could possibly cause long term hearing damage. When you are fitted with custom made ear pieces, they shield you from external noise so there is really no need to listen to audio at excessively high levels.

Q. Will having the impression taken hurt?

No, you will just experience absolute silence for about 5 to 10 minutes as the impression material cures or sets in your ears. Enjoy the experience! Please note we are Registered Audiologists and we will only take impressions of your ears if all is safe and clear of wax. We will advise you should your ears be occluded with wax and need syringing by your GP surgery.

Q. What is the difference between ER and Non-ER earplugs?

ER rated plugs have been clinically tested to ensure the meet the exacting standards as set out in the EN352-2:1993. Ear plugs with ER filters incorporate individually calibrated filters (usually 9,15 or 25 dB) designed to attenuate all sound frequencies at the same level. Thus giving you a reduced volume but without losing the clarity of what you are listening to. Non filtered plugs give a flat attenuation across the whole frequency spectrum, as a result they give an approximately 30dB attenuation.

Q. How long does it take to receive custom made earplugs?

You should receive your custom made earplugs back from us between 2 and 3 weeks. They will come direct from the manufacturers to you. You then have 30 days in which to let us know should you have any fit problems - we pride ourselves in this after service we provide. Always contact us regarding any queries.

Q. How much noise can a person tolerate?

The strength of a sound is determined by the pressure of the sound waves and is expressed in decibels: dB(A). dB(A) measurements are corrected to the sensitivity of the human ear. The quietest audible sound is 0dB(A). The threshold of pain is at 120dB(A).

dB(A) recommended maximum exposure:

85dB = 8 hours
88dB = 4 hours
91dB = 2 hours
94dB = 1 hour
97dB = 30 minutes
100dB = 15 minutes
103dB = 7.75 minutes
106dB = 3.75 minutes
