Welcome to ISCE




Sound Measurement Techniques

Learn how to measure the acoustic parameters that affect sound system performance and design.

You Will Learn:

• How sound level meters work and which measurement parameters and settings to use.
• Noise measurement terminology; A and C weighting curves, fast, slow integration times and Leq measurements.
• Octave, 1/3 octave and narrow band frequency resolutions and their uses.
• What ‘real time’ analysis can and cannot do.
• How to make impulse response measurements and what these can tell you.
• How to make reverberation time measurements and estimate reverberation times.
• How rooms can affect sound and how to determine and quantify such effects.
• Direct and reverberant soundfield analysis.
• Critical distance and its importance in sound system measurement.
• How to measure sound distribution and variation.
• System polarity measurements.
• How to make speech transmission index measurements and verify the intelligibility.
• Measuring the frequency response of a sound system.
• Use of acoustic measurement apps and devices.

The course will include live demonstrations and a hands-on session where participants get to make their own measurements.

Who Should Attend:

Everyone involved in the installation and testing of sound systems or voice alarm systems.


Principles of Networking

Learn how networks operate and how to configure devices to connect to them.

You Will Learn:

• Network types and technologies: their applications and limitations
• Ethernet: the difference between switches and hubs, MAC addresses, full and half duplex
• TCP/IP: UDP and TCP, addressing, subnets and routing
• Network configuration: static vs DHCP, DNS, gateways and firewalls
• Network design: building your own network
• Network troubleshooting: identifying and resolving common problems
• Wireless networks: RF spectrum and channel overlap, SSID, authentication and encryption
• Network data structures: what makes up Ethernet frames and IP packets and how they work together
• Data delivery: Unicast, Broadcast and Multicast

Who Should Attend:

Anyone involved in specifying or configuring network devices.


Advanced Principles of Networking

Learn the principles and technologies used to create high performance data networks with the robustness and reliability required for networked audio.

Key principles covered:

• Improving network reliability through redundancy
• Maximising available bandwidth
• Prioritising audio data to maintain audio quality
• Network security
• Monitoring

Key technologies covered include:

• Spanning Tree (including RSTP and MSTP)
• Link Aggregation
• QoS (including CoS and DSCP)

Who Should Attend:

Anyone involved in setting up networks for real-time audio and video applications and already has a good understanding of the basics of Ethernet and IP.  Ideally, delegates should have previously attended the Principles of Networking course or be familiar with the material covered.
