Acoustic Modelling
Predictive Modelling for Complex Environments
Hammond Electroacoustics provides high-resolution acoustic modelling for large and complex spaces such as stadia, arenas, cathedrals, and transport terminals, down to small critical-listening rooms. Our collection of specialist computer modelling software such as CATT-Acoustic, EASE, COMSOL and bespoke MATLAB applications, allows us to predict how sound behaves in real-world conditions, including the impact of audience occupancy on speech intelligibility. This service enables stakeholders to make informed design choices early, reducing costly errors and ensuring systems meet both client expectations and regulatory standards.
PAVA System Design & Speech Intelligibility Optimisation
Public Address and Voice Alarm Systems
We design and optimise PAVA systems to meet the most demanding compliance and performance standards. Our expertise includes BS 5839-8, BS EN 54, BS 7827 and BS 60268. We work across entertainment and sports venues, transportation, nuclear and other large public spaces, including the design of the largest PAVA system currently in the UK. As a subject matter expert in STI and intelligibility assessment, Hammond Electroacoustics evaluates how sound systems perform under real-world conditions, including occupied spaces. We identify shortcomings in conventional testing methods and provide actionable recommendations.
Expert Review & Consultancy
Research-Informed Guidance for Complex Projects
For teams facing challenging acoustic problems, we provide bespoke consultancy and expert review, combining practical design experience with PhD-level research insights. We support R&D projects, system troubleshooting, and high-stakes design decisions. Our consultancy services are ideal for clients who need technical assurance, research-backed advice, or advanced simulation insights. By integrating peer-reviewed research with practical know-how, we provide assurance that complex projects are grounded in proven methods while remaining innovative and future-ready.
AURALISATION
Virtual Listening using Auralisation Techniques
Through auralisation methods, our clients can experience their space or sound system virtually before it’s built or commissioned, allowing optimisation, A/B testing, and a true understanding that is easier to interpret than a visual representation such as a heat map of coverage or numerical acoustic metrics. Auralisation provides decision-makers with a powerful demonstration tool, supporting collaboration between architects, engineers, and non-technical stakeholders.
Sound Reinforcement Systems
Sound Systems for Audiences
Hammond Electroacoustics provides expert sound reinforcement design and optimisation for live events, corporate spaces, and large venues. We ensure that speech and music are intelligible and well-balanced across all listening positions, even in acoustically challenging environments. Our approach combines advanced acoustic modelling, practical on-site assessment, and system optimisation, allowing clients to achieve consistent coverage, clarity, and immersive experiences.
