00:00:00.080 --> 00:00:04.920
for people like me who have made a living out of the smooth audible

00:00:03.520 --> 00:00:10.240
chocolate of their voices microphones have become a tool on

00:00:07.879 --> 00:00:13.719
which our variability to put food on our tables is dependent and while your

00:00:12.040 --> 00:00:17.800
average person might not feel the same way about them and may never set foot

00:00:15.240 --> 00:00:21.560
anywhere near a Sound Studio chances are they would still find life a bit more

00:00:19.800 --> 00:00:26.960
challenging had the microphone never been invented from those found on

00:00:24.039 --> 00:00:31.439
telephones to drive-thru menus to the headsets worn by professional Gamers and

00:00:29.320 --> 00:00:36.520
air traffic controllers alike these things have become indispensable to all

00:00:34.280 --> 00:00:41.399
but the most rugged Mountain folk Among Us so microphones first came into

00:00:38.840 --> 00:00:46.600
existence around the year of 600 BC in the form of masks which would carry a

00:00:44.200 --> 00:00:51.320
stage performers voice across the expanse of a large Amphitheater simple

00:00:49.079 --> 00:00:56.280
amplification Remains the general goal behind Soundwave manipulation until a

00:00:54.199 --> 00:01:01.800
man in the mid 19th century by the name of Antonio miuchi invented the tetrao

00:00:59.920 --> 00:01:06.960
let's try that again in English telephone and with that the races were

00:01:04.760 --> 00:01:11.560
on to see which inventor could innovate and improve this device most

00:01:08.960 --> 00:01:16.280
successfully now modern microphones or mics tend to fall into one of two major

00:01:14.040 --> 00:01:22.000
groups depending on what type of audio transducer the device which transforms

00:01:18.799 --> 00:01:24.280
sound into an electrical signal is used

00:01:22.000 --> 00:01:29.159
the first of these transducer Styles is known as Dynamic and is normally the

00:01:26.759 --> 00:01:34.560
type one sees their favorite pop singer using on stage these operate by way of a

00:01:32.159 --> 00:01:39.079
plastic diaphragm that manipulates a coil located at its rear which has been

00:01:36.799 --> 00:01:43.360
wrapped around a magnet whenever sound waves cause the diaphragm to undulate

00:01:41.399 --> 00:01:47.240
the coil is bounced back and forth over the magnet surface with the movements

00:01:45.200 --> 00:01:51.920
being registered and transformed into a signal these mics have the advantage of

00:01:49.600 --> 00:01:57.880
being able to record high volume sources such as directly sung vocals without

00:01:55.119 --> 00:02:02.719
easily distorting but the magnets which they use also restrict their ability to

00:02:00.119 --> 00:02:06.840
be shrunk below a certain size this coupled with the needed input strength

00:02:04.600 --> 00:02:11.440
to move the coil along the magnet leave them wanting sometimes in the

00:02:08.720 --> 00:02:16.720
Departments of high frequency detail and low volume pickup the second transducer

00:02:14.400 --> 00:02:21.000
type is referred to as a condenser and it also uses a diaphragm to register

00:02:18.840 --> 00:02:25.480
incoming sound waves but instead of bouncing a coil around a magnet the

00:02:23.200 --> 00:02:30.560
diaphragm is placed adjacently to a powered sensor plate which detects the

00:02:27.760 --> 00:02:35.080
changing gap between these as it shrinks and grows with stimulation which gives

00:02:32.640 --> 00:02:39.800
them an advantage in terms of size and sensitivity that makes them ideal for

00:02:36.920 --> 00:02:42.959
things like phones headsets and small body worn

00:02:41.040 --> 00:02:48.400
jobbies like the little one that I'm wearing in here they do require a

00:02:45.480 --> 00:02:53.080
discrete power source for operation where magnet driven designs do not and

00:02:50.800 --> 00:02:57.040
also the reduced size between the plate and the diaphragm when compared to the

00:02:54.920 --> 00:03:01.720
length of the coiled magnet means they tend to top out and distort more easily

00:03:00.239 --> 00:03:06.959
with loud noises now what kind of transducer a

00:03:04.440 --> 00:03:11.239
microphone uses doesn't mean a whole lot unless it actually picks up sound from

00:03:08.799 --> 00:03:17.239
the intended source and hopefully that only this is where the role of polar or

00:03:14.560 --> 00:03:21.040
pickup patterns comes in which determine where the input is received from

00:03:19.280 --> 00:03:25.519
relative to the microphone's location now there are many pattern styles for

00:03:23.360 --> 00:03:30.000
different uses but the three basic families consist of omnidirectional

00:03:28.239 --> 00:03:34.280
which pick up sound in a sphere surrounding the mic equally

00:03:32.000 --> 00:03:37.920
unidirectional or cardioid with its pattern looking something like a

00:03:35.480 --> 00:03:42.560
mushroom head and fading audio that's not directly in front of the microphone

00:03:40.040 --> 00:03:47.879
and bidirectional which resembles a figure8 and you guessed it goes both

00:03:45.519 --> 00:03:52.400
ways the noise cancelling feature many microphones use actually operates by

00:03:50.360 --> 00:03:56.840
directing a pickup away from the intended Source then subtracting

00:03:54.480 --> 00:04:00.640
anything it detects from the overall sum of both inputs with more advanced

00:03:58.560 --> 00:04:04.959
systems using even more more than two microphones now although microphones

00:04:02.879 --> 00:04:09.439
come in any transducer and pickup combination a user could Desire with

00:04:07.239 --> 00:04:14.799
many boasting adjustable patterns on the Fly it's important to note that the

00:04:11.519 --> 00:04:16.840
mixer processor or amplifier not to

00:04:14.799 --> 00:04:20.199
mention file format types and the and speakers that are used to enjoy the

00:04:18.239 --> 00:04:25.080
audio play a role in the experience as well and while this may seem like a bit

00:04:22.680 --> 00:04:29.840
much for those who are uninitiated I can assure you all that it is at least much

00:04:27.840 --> 00:04:34.680
more simple and convenient a way of communicating than the smoke signals

00:04:32.280 --> 00:04:38.520

00:04:36.400 --> 00:04:42.840
