EST. 1967 · BASED IN WORTHING, SUSSEX
For over 60 years, System Design has delivered specialist public address, induction loop and acoustic sound solutions for some of Britain's most demanding spaces — from intimate chapels to grand cathedrals, concert halls and live event venues across the UK and Europe.
"If it were ethical for me to tell people to go to System Design, I would!"
Cardinal Cormac Murphy O'Connor
Over six decades we’ve been trusted with some of the most demanding acoustic spaces in the UK and beyond.
Royal Festival Hall · Hayward Gallery · Sizewell B Simulation Building · Lord Rayleigh’s Dairy (then Europe’s largest milk processing plant) · 2010 Papal Visit to England · Brompton Oratory · Numerous cathedrals and abbeys · English‑speaking parishes in Germany and Switzerland · Wales and the Channel Islands.
In 1989, we designed and installed the largest induction loop system ever at Chichester Cathedral.
ABOUT PETER HEARN
Four decades of expertise, built on a passion for music and precision engineering.
Peter Hearn — Managing Director & Lead Engineer
Peter joined his father Brian to form the partnership in 1985, bringing a background in music composition, live performance, and electronics. His final electronics project produced what may be the world's first automatic tone control — and established his specialist expertise in induction loop design for the hard of hearing. Together, Brian and Peter repositioned System Design during the 1980s recession as a recognised specialist in church sound, a field where few others could compete.
Peter leads with a clear philosophy: deliver sound systems that are fit for purpose, aesthetically considered, and built to last. With 60 years of combined experience, the team continues to refine and innovate.
"It feels very reassuring to be surrounded by such competence."
Fr Tony Clarke, St Mary's Worthing
Every system is bespoke, designed for your space and your people.

Full‑range sound systems, from a delicate chapel to a pumping nightclub, always tuned for clarity and intelligibility.
Induction Loop / Auracast Systems
Advanced hearing solutions for any space - from induction loops in chapels to record-breaking cathedrals, to Auracast delivering next-gen audio direct to compatible devices.
Live Streaming · Growing Service
From simple podcasts to fully automatic live streaming setups, designed for reliability and ease of use.
How It Works
A clear, five‑step process from first contact to long‑term support.
1. Get in touch
Call or email with your venue address, type of location, and what you need: repair, upgrade or advice.
2. On‑site meeting & survey
Peter will arrange a visit to your venue. Understanding the acoustic environment firsthand is essential — no two spaces are the same.
3. Full binding quotation
You receive a full binding quotation, so you know exactly what you will pay and what will be delivered.
4. Installation with minimal disruption
We work carefully to keep any existing system operational throughout the installation. Your space continues to function while we work.
5. Handover & ongoing support
On completion, you'll be fully briefed on how to operate the system — though in most cases, there's nothing to operate. 90% of our systems are fully automatic. We remain available for support and maintenance long after installation.
Words from those we've worked with.
