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!

Sep 04, 2015

  1. You may be hearing a ground loop caused by another component in the room. Try the speakers in another room along with your A/V receiver/amplifier and see if the problem persists.
  2. Try a new set of cables. Sometimes cables that aren’t properly shielded can cause interference.
  3. Invest in a power conditioner that offers isolation and surge protection.
  4. Connect the speakers themselves into the main L/R outputs of the receiver, if they sound fine you know it’s not a problem with the speakers.
  5. Check to make sure no wires are running across another electrical cord, metal duct or any other piece of equipment.

A Brief History of Audio

May 20, 2015

From the first tinfoil cylinder to today’s advanced equipment, the world of audio has come a long way. Think about what life was like before microphones, headphones and speakers were invented. How was anyone able to hear anything? Take a look below to find out how audio first began and how it has evolved over the years:

It all started with Thomas Alva Edison working in his lab in 1877. It was then, when he succeeded in recovering Mary’s Little Lamb from a strip of tinfoil wrapped around a spinning cylinder. This was the beginning of audio as we know it.

A year later, the first music was put on a record, you may know it by the tune of “Yankee Doodle.” Then, roughly 10 years later Edison introduces the first electric-motor driven phonograph and the first “talking movie” comes around in 1913. Edison used his Kinetophone process to make this work – a cylinder player mechanically synchronized to a film projector.

In 1941, commercial FM broadcasting comes to fruition in the United States just before the first stereo tape recordings were created by Helmut Kruger in Berlin. For the next few decades, major advancements are made in the audio world which brings us to the Winter Olympics in 1998. The opening performance begins with Beethoven’s “Ode to Joy” which was masterfully played and sung by synching live audio feeds from five continents across the globe. Pretty amazing!

At CitiView Audio Visual we are always looking forward to the future of audio. But for now, you can count on us any time you need audio services for your live event! Give us a call at 212-632-5196 for more information!

Nov 06, 2015

The ways in which businesses and clients communicate have taken on a whole new shape in the last couple of years.

Web Conferencing

When you are doing business across the country or across the globe, it’s difficult to get everyone in the same physical location. Thanks to web conferencing, we now have the ability to set up meetings any time of day as if everyone was face-to-face. But you can’t host a successful web conference without the right equipment. If you don’t have the capabilities of multi-camera switching, picture-in-picture or a content delivery system you’re missing out.

Audio

A few years back, a webcam with a pinhole mic was enough to get the job done. However, technology has evolved since then and audio transmission is much clearer. But this means you’ll need a higher quality mic. Don’t worry, we’ll take care of that for you!

Video

If you have web conferencing software and a decent mic, it won’t do you much good without a quality camera. Failing to use an HD camera with proper background lighting can make your company look unprofessional and outdated.

At CitiView Audio Visual we understand that meetings pop up and presenters’ needs change on-site. Our staff will respond quickly and professionally so give us a call at 212-632-5196.
