University of Exeter creating the Calm Protectors

University of Exeter will be creating 3 prototypes as part of a continued partnership between Exeter University and Primary Engineer.

University of Exeter are one of our University Prototyping Partners for Devon and Cornwall as part of our annual engineering competition which asks pupils aged 3-19 ‘If you were an engineer what would you do?’ and encourages pupils come up with creative solutions to real-world problems.

Introduction

University of Exeter will turn Year 2 pupil Elouise’s Calm Protector into a reality with their prototype.

University of Exeter have selected this design to turn into a prototype over the 2023/2024 academic year and it will be unveiled at the Devon and Cornwall Awards Ceremony and Public Exhibition during the Summer term.

They chose this design because they recognise that there is an increase number of children and adults suffering from hearing sensitives which can lead to learning problems and self-esteem problems and there’s not enough care/products available to help people.

Beginning the Prototype

The team have researched several market options including in ear, over ear, on ear and ear muffs to
limit auditory sensory overload. They have already created a very very low-fidelity prototype.

Their final solution will be 3D printed and mocked up on CAD soon. There are several
sketches provided to highlight the development.

But ultimately want a fully adjustable earplug that is discrete, capable of blocking unwanted
background noise; anywhere from 10% – 95% of unwanted auditory noise eliminated. Utilising a novel
conical shape design, that will rotate and allow for a staggered audio holes to be completely blocked,
partially open or entirely open.

We can’t wait for the next update on this prototype!
