Brief History of the Microphone

Jul 10, 2015 by Steve Rick in  Uncategorized

How does a microphone work? When was it invented? Why do we use them today during just about every live event? See below to find out the answers while we dive into a brief history of the microphone.

How Does It Work?

Sound waves need to be converted into electrical voltages and then converted back into soundwaves so an audience can hear the message through speakers. The microphone is a device that makes this all possible and they were first used with early telephones and radio transmitters.

How Did It All Begin?

Sir Charles Wheatstone was the first person to coin the phrase “microphone” in 1827 but it wasn’t until 1876 when Emile Berliner invented the first microphone used as a telephone voice transmitter. Soon after, the Bell Telephone company purchased the patent from Berliner for $50,000.

In 1942, the first ribbon microphone was invented for radio broadcasting and in 1964, Bell Laboratories received a patent for an electret microphone. This revolutionized the microphone industry with close to one billion produced each year. As technology continued to advance, more dynamic microphones were created which leaves us with the clear sound we hear today!

Make The Switch To LEDs!

May 04, 2015

Why switch to LEDs? The days of incandescent bulbs are over as more and more people are trading them up for LED bulbs. Longer lifespan, less energy and less heat are just a few of the many reasons to make the change. We switched, have you?

Less Energy 

LEDs produce far less heat than standard incandescent bulbs, therefore they endure much less heat loss. As a result they are more energy efficient, sometimes up to 85% more than the vacuum/filament method used in incandescents.

In addition to using less energy, you’ll use fewer bulbs. Tired of replacing your bulbs multiple times per year? Well, some LED bulbs can last up to 50,000 hours. That’s a long time if you ask us!

The Green Choice

We think the decision is simple, but if you’re still not convinced here are a few more benefits. Even though you may have spend a few more dollars upfront, LEDs can save you hundreds of dollars in the long run. Consider this: even if you spent $100 for a single bulb, you’ll only need one every 10-20 years. Spending less money on home lighting can save you about 7% on your electric bills which will be far more than the initial $100.

At CitiView Audio Visual, we’ve made the switch to LEDs. While still providing the quality and brightness you expect from exceptional stage lighting, LED lighting is not only the green choice, it’s the best choice. So give us a call the next time you’re hosting an event, and let us take care of the lighting!

You can thank expert audio engineers and their restoration software for taking care of these undesirable sounds and creating “music to your ears”!

With home recording on the rise due to factors such as low budgets and little time, “dirty audio” is becoming more prevalent as well. Just think, while you may decide to belt out your latest song in your room it wasn’t built to filter out extraneous sounds.

How To Test Speaker Wires and Connections

Jul 08, 2015

What’s one of the most common problems with speakers? Their wires get tangled up in a pile and the hardest part is figuring out where they are supposed to go. But you don’t have to spend hours untangling the mess, you can trace the wires with common household batteries.

Speakers and their wires have a positive and negative polarity and so do batteries. Therefore you can hold one speaker wire to one of the batter terminals (using AA or AAA) and hold the other wire to the remaining terminal to find out where they are supposed to go.

To do this, take one of the wires and repeatedly touch and disconnect it from the terminal. You should hear a static sound each time the wire touches the terminal and this will allow you to identify the speaker. It’s a good idea to label each wire with is corresponding speaker so you won’t get them mixed up again.

When you need professional audio solutions, you can count on the highly skilled technical sound engineers at CitiView Audio Visual. Give us a call today at 212-632-5196 for more info!
