for people like me who have made a living out of the smooth audible
0:03
chocolate of their voices microphones have become a tool on
0:07
which our variability to put food on our tables is dependent and while your
0:12
average person might not feel the same way about them and may never set foot
0:15
anywhere near a Sound Studio chances are they would still find life a bit more
0:19
challenging had the microphone never been invented from those found on
0:24
telephones to drive-thru menus to the headsets worn by professional Gamers and
0:29
air traffic controllers alike these things have become indispensable to all
0:34
but the most rugged Mountain folk Among Us so microphones first came into
0:38
existence around the year of 600 BC in the form of masks which would carry a
0:44
stage performers voice across the expanse of a large Amphitheater simple
0:49
amplification Remains the general goal behind Soundwave manipulation until a
0:54
man in the mid 19th century by the name of Antonio miuchi invented the tetrao
0:59
let's try that again in English telephone and with that the races were
1:04
on to see which inventor could innovate and improve this device most
1:08
successfully now modern microphones or mics tend to fall into one of two major
1:14
groups depending on what type of audio transducer the device which transforms
1:18
sound into an electrical signal is used
1:22
the first of these transducer Styles is known as Dynamic and is normally the
1:26
type one sees their favorite pop singer using on stage these operate by way of a
1:32
plastic diaphragm that manipulates a coil located at its rear which has been
1:36
wrapped around a magnet whenever sound waves cause the diaphragm to undulate
1:41
the coil is bounced back and forth over the magnet surface with the movements
1:45
being registered and transformed into a signal these mics have the advantage of
1:49
being able to record high volume sources such as directly sung vocals without
1:55
easily distorting but the magnets which they use also restrict their ability to
2:00
be shrunk below a certain size this coupled with the needed input strength
2:04
to move the coil along the magnet leave them wanting sometimes in the
2:08
Departments of high frequency detail and low volume pickup the second transducer
2:14
type is referred to as a condenser and it also uses a diaphragm to register
2:18
incoming sound waves but instead of bouncing a coil around a magnet the
2:23
diaphragm is placed adjacently to a powered sensor plate which detects the
2:27
changing gap between these as it shrinks and grows with stimulation which gives
2:32
them an advantage in terms of size and sensitivity that makes them ideal for
2:36
things like phones headsets and small body worn
2:41
jobbies like the little one that I'm wearing in here they do require a
2:45
discrete power source for operation where magnet driven designs do not and
2:50
also the reduced size between the plate and the diaphragm when compared to the
2:54
length of the coiled magnet means they tend to top out and distort more easily
3:00
with loud noises now what kind of transducer a
3:04
microphone uses doesn't mean a whole lot unless it actually picks up sound from
3:08
the intended source and hopefully that only this is where the role of polar or
3:14
pickup patterns comes in which determine where the input is received from
3:19
relative to the microphone's location now there are many pattern styles for
3:23
different uses but the three basic families consist of omnidirectional
3:28
which pick up sound in a sphere surrounding the mic equally
3:32
unidirectional or cardioid with its pattern looking something like a
3:35
mushroom head and fading audio that's not directly in front of the microphone
3:40
and bidirectional which resembles a figure8 and you guessed it goes both
3:45
ways the noise cancelling feature many microphones use actually operates by
3:50
directing a pickup away from the intended Source then subtracting
3:54
anything it detects from the overall sum of both inputs with more advanced
3:58
systems using even more more than two microphones now although microphones
4:02
come in any transducer and pickup combination a user could Desire with
4:07
many boasting adjustable patterns on the Fly it's important to note that the
4:11
mixer processor or amplifier not to
4:14
mention file format types and the and speakers that are used to enjoy the
4:18
audio play a role in the experience as well and while this may seem like a bit
4:22
much for those who are uninitiated I can assure you all that it is at least much
4:27
more simple and convenient a way of communicating than the smoke signals
4:32
that we used to use speaking of communication if you want to improve
4:36
your skills in a wide variety of areas including communication you should
4:40
definitely check out linda.com we're well into 2015 and Linda thinks you know
4:45
what maybe it's time to start investing in yourself and learning something new
4:49
it's used by millions of people around the world they have more than
4:52
3,000 courses available with topics like business web development photography
4:57
video editing visual design they have software training like Excel WordPress
5:01
and Photoshop and their all their courses are taught by industry experts
5:05
with new courses added every week so whether the goal is to like do better at
5:10
your you know hobby or whether it's to find a new job or ask your boss for a
