Welcome to the World of Classroom Audio Distribution Systems!
In today's educational landscape, enhancing student learning experiences is a top priority. One innovative approach that many schools are adopting is the use of Classroom Audio Distribution Systems (CADS). These systems are designed to improve the listening environment in classrooms, thereby boosting student engagement and comprehension. However, to truly harness the benefits of CADS, it's crucial to understand their proper usage and limitations.
Understanding the Basics
At its core, a CADS is not just a sound amplification system but a tool to distribute sound evenly across the classroom. This ensures that every student, regardless of where they sit, can hear the teacher clearly without straining. It's important to note that CADS are intended for students with normal hearing or single-sided deafness. Students with hearing loss who use hearing aids require personal FM systems for optimal auditory access.
Common Questions Answered
Here are some frequently asked questions from our workshops, along with their answers:
- How loud should the system be? The system should be set so that the teacher's voice is no louder than a normal conversation. It's helpful to have a colleague listen while you teach to ensure the volume is appropriate.
- Why use boom microphones? Boom microphones provide superior sound quality and allow natural head movement. They should be worn on the head, not around the neck, to avoid sound quality issues.
- Do Infra Red (IR) systems work the same way? Yes, they do. However, they use a different microphone array, so refer to the manufacturer's instructions for proper use.
- How close should the microphone be to my mouth? The microphone should be 2.4 – 4.0 centimeters from your mouth to avoid popping sounds during speech.
- When should the system be turned on? Turn it on during group listening tasks, like directions or reading. Remember to turn it off or mute it when leaving the room or having private conversations.
- Why do microphones need frequent replacement? Microphones are delicate. Use a holder or fanny pack to protect them, and unplug them properly to avoid damage.
- What if something isn't working? Contact the distributor of your system. Here are some contacts for Northern Alberta:
- FrontRow: Genesis Communications, Jim Pshyk, 780‐455‐3000
- TOA: Alpha Net, John, 780‐413‐0947
- Azden: Concept A/V, Christian, 780‐461‐1177
- What is the lifespan of rechargeable batteries? It's recommended to replace them each school year as they lose their ability to hold a charge over time.
- Where can I find more research? The Front Row website offers extensive resources. Feel free to reach out for more information if needed.
Final Thoughts
Classroom Audio Distribution Systems are a valuable tool in creating an inclusive learning environment. By understanding and implementing the proper use of these systems, teachers can significantly enhance the auditory experience for students, leading to better educational outcomes. Remember, these systems are meant to assist normal hearing students and should not replace personal FM systems for those with hearing impairments.
