The process of taking the ear impressions are carried out by fully qualified and certified professionals.

All our technicians are trained to the highest level with regular updates on new procedures and yearly assessments.  

They are all BSHAA certified and covered by our comprehensive medical indemnity insurance.

 

As part of our technical staff we have fully qualified audiologists who are on hand to assess any issue, which may arise during the standard ear health examination.

 

The process begins with a brief client history where we discuss recent health issues that can affect the impression taking.  This includes recent colds and flu.   After the outer ear has been examined the technician uses a fibre optic otoscope to check the inside of the ear canal and the health of the Tympanic Membrane.   If the canal and tympanic membrane is considered healthy then the technician will proceed to the next step in the process.

All impression technicians are qualified to remove excess wax using microsuction or ear irrigation if necessary.
 
A small cotton dam is inserted into the canal at a point just in front of the second bend in the canal.   This ensures that the impression material does not ingress too close to the ear drum.   Next a small block of dense polystyrene is inserted in to the clients mouth to ensure that the ear canal remain at its widest point during the most important part of the process. (this ensures the tightest fit of the finished product)

 

The technician will then mix the appropriate amount of Room Temperature Vulcanising Silicone and uses a specially designed syringe to fill the ear canal and the entire concha of the ear.   When this material sets (approximately five minutes) the moulds are removed from the ear, packaged and taken to the laboratory for manufacture.   The laboratory is presently the largest of its kind in Europe and has a capacity for thousands of units a week.

 

When the moulds arrive at the office they are placed in a specially designed scanning unit that converts the mould into a perfect digital image.   This image is then sent to one of the four new Projet 3510 MP 3D digital scanners. In an overnight process that takes place in a temperature and pressure controlled secure area the product is produced using the latest Microflex Extreme material.

This material is recognised as the most advanced available today.

 

This new and unique process guarantees that the finished product is the truest likeness to the original impression taken and guarantees both comfort and acoustic performance over years of continued use.

 

Upon placing an order for custom moulded protection, one of our representatives will arrange a suitable date to visit your site to take the necessary ear impressions.

 

During the procedure we provide a full ear health check before injecting a soft material in to the canal. This material cures in minutes, giving us the truest representation of the ear canal and concha.

 

Our Hearing Protection Specialist will also survey the environment and the intended application to ensure the correct type of attenuating filter is applied to the finished product.

 

After the site visit is complete, the ear impressions are sent to the laboratory where they are manufactured ready for use.
