Q: What's the difference between a voice amplification system, a personal amplification system and an assistive listening system?
A (vocologist): Nothing. These terms are basically synonymous.
Q: I've looked at some of the specs on websites, and I'm not sure how to compare the different systems. For example, how much power do I need? What else should I be looking for?
A (scientist): For the average teacher in the average classroom, you probably want to boost your sound level at least 10-15 decibels.
A (teacher): Rather than how MUCH power you need, I'd focus on how you're going to get that power - are you looking for a portable system or a permanent one?
Q: What would you recommend?
A (teacher): Only you can answer that question. Take some time to figure out what you want and how you're going to use it. Then, of course, you need to assess what your resources for paying for the system are. That will really narrow down your search.
A (vocologist): Either way you go, you'll be doing your voice a load of good. Many teachers in my practice say that this one change - using amplification - made a huge difference in their teaching effectiveness and their fatigue at the end of the day.
Q: From a cost standpoint, the portable system seems more attractive. What are the downsides to a portable system?
A (scientist): You have to wear a portable system. While they aren't very heavy, they may bother you - at least for a while. Also, the microphone with a portable systems plugs into the fanny-pack amplifier/speaker combo. Thus, it is more obvious you are using amplification.
A (teacher): You have to remember to re-charge the system every night, because the charge only lasts ten hours or so.
Q: What are the advantages and disadvantages of the wireless system?
A (scientist): With this system, teachers can wear a wireless mic, but it might take a while to get it installed because you have to get permission to alter the classroom.
A (vocologist): However, you can use that to your advantage. Some schools decide to put amplification into all their classrooms at once, which can be more economical in the long run. Therefore, you've not only solved your own voice problems, but you've prevented other teachers' voice problems as well.
A (teacher): A lot depends upon how mobile you want to be. I'm the drama coach, so it made sense to me to be able to use my system to teach all day, then take it with me to the auditorium for play rehearsals.
Q: OK, I get the technical side of how these work, but how practical are they?
A (teacher): I love my system. I can reach every student in the room even those sitting in the back. I don't have to repeat as much, and my students' comprehension has increased. I've been able to work it into my instruction in so many ways. For example, students get to use it when they read aloud to the class. It gives even shy kids a boost of confidence. I'd let you take away my textbooks before I gave up my sound system!
A (vocologist): My clients who have them say it takes a few days to get used to them. But I'm surprised how little disruption they report from students. This may be because it's becoming increasing common to see people use microphones: aerobics teachers, clerks in large stores, rock singers .
Q: Are they durable? For example, what would happen if the system fell to the floor?
A (teacher): I've had mine for years. Yes, I've banged it on the door and even dropped it on my desk. I haven't had any problems. These things are very sturdy.
Q: So, do amp systems work best for people who already have voice problems or for those who are trying to prevent voice abuse?
A (vocologist): Both. Ideally, we'd like to see teachers use an amplification system before voice problems occur. But, sometimes teachers may not know they are at vocal risk until they have symptoms. Removing the source of voice problems is often enough to clear up the problem itself.
Q: What about teachers who also coach sports? Can they use it for coaching?
A (scientist): Yes. You will find a portable system especially helpful for coaching outdoor sports. If you are a swimming or diving coach, however, and echoes are the problem, the amplification system may not be all that helpful at the indoor pool. Amplification doesn't solve the problem of reflected sound.
Q: Is there a way to predict if an amplification system would benefit me?
A (scientist): If you're not sure, contact a vendor. They may allow you to try out various systems for a trial period.
A (vocologist): Keep in mind that an amplification system will only boost volume. If you're worried about something else, like an accent, stuttering or mumbling, it won't help you out there.
A (teacher): You only have to think about how many sick days you take or should have taken because of a sore throat or other voice problem. And how about your quality of life? It's exhausting teaching with a tired voice.
Q: Can you wear a wireless microphone with a portable system?
A (scientist): No, the cable running from the mic to the amplifier/speaker is necessary to carry your voice signal.
Q: What's in the future for amplification systems?
A (scientist): A welcomed recent improvement is the use of infra-red, rather than FM radio signals, in the wireless systems. Occasionally, the FM systems picked up radio or other classrooms' signals. The newer systems eliminate the risk of strange, uninvited signals being broadcast in the classroom!
A (teacher): I just wish these would become as standard as blackboards and books. My system has been more beneficial to me and my students than a lot of the other educational tools at my disposal. If nothing else, each school should have a system or two for teachers to borrow when they are having a "bad voice day."
A (vocologist): Just look at the math: 2 or 3 days of substitute teachers' pay would be enough to purchase a portable amplification system and mic.
