A new date has been confirmed for ISCVE’s Designing for Speech Intelligibility training course, taking place on Thursday 25 June 2026 at Audiologic.

This course is aimed at audio and AV engineers, system designers, consultants, and installers involved in the specification, design, and optimisation of sound systems where speech clarity is critical.

Places are limited, and early booking is advised.

Overview

This course provides a structured, engineering-led approach to achieving intelligible speech reproduction within sound reinforcement and voice alarm systems.

It examines the interaction between electroacoustic design, room acoustics, and signal processing, equipping attendees with the knowledge required to predict, measure, and optimise system performance.

Why Speech Intelligibility is Critical

Speech intelligibility is a key performance criterion in many applications, including public address, emergency voice alarm, transport infrastructure, and large-scale venues.

System performance is often compromised by poor acoustic conditions, excessive reverberation, inadequate loudspeaker coverage, and low signal-to-noise ratios. Failure to address these factors can result in non-compliance with standards, reduced usability, and increased risk in safety-critical environments.

Course Content

The course covers the core technical principles and methodologies used in professional system design, including:

• Acoustic fundamentals and their impact on intelligibility
• Measurement and interpretation of Speech Transmission Index (STI)
• Loudspeaker directivity, coverage mapping, and system configuration
• Effects of reverberation time (RT) and background noise levels
• Signal processing techniques including EQ, delay, and dynamics control
• System alignment, tuning, and verification methods
• Practical approaches to improving intelligibility in challenging environments

Why Attend

With increasing emphasis on intelligibility standards and system performance, particularly in safety-critical applications, this course provides essential knowledge for professionals responsible for audio system design and delivery.
