Dialogue: 0,0:02:51.53,0:02:54.81,Default,,0000,0000,0000,,It starts at a very\Nlow volume.
Dialogue: 0,0:02:54.81,0:02:58.61,Default,,0000,0000,0000,,And as soon as you hear it, you\Nhit a buzzer or say, yes.
Dialogue: 0,0:02:58.61,0:03:02.79,Default,,0000,0000,0000,,And then they create\Nthis curve.
Dialogue: 0,0:03:02.79,0:03:06.59,Default,,0000,0000,0000,,So the blue curve is a\Ntypical curve of a

Dialogue: 0,0:03:08.41,0:03:12.33,Default,,0000,0000,0000,,So what you can see here-- that,\Nat the low frequencies,
Dialogue: 0,0:03:12.33,0:03:13.70,Default,,0000,0000,0000,,their hearing is quite well.
Dialogue: 0,0:03:13.70,0:03:15.61,Default,,0000,0000,0000,,That's very typical.
Dialogue: 0,0:03:15.61,0:03:20.12,Default,,0000,0000,0000,,Their hearing starts to get\Nworse in the high frequencies.
Dialogue: 0,0:03:20.12,0:03:24.66,Default,,0000,0000,0000,,And bear in mind that the\Ndecibel scale is actually
Dialogue: 0,0:03:24.66,0:03:25.78,Default,,0000,0000,0000,,logarithmic.
Dialogue: 0,0:03:25.78,0:03:31.02,Default,,0000,0000,0000,,So if you have a hearing loss of\N60 decibels, it's 1 million

Dialogue: 0,0:03:33.42,0:03:36.79,Default,,0000,0000,0000,,So it's not linear.
Dialogue: 0,0:03:36.79,0:03:41.27,Default,,0000,0000,0000,,Another thing that gets measured\Nat an audiogram is
Dialogue: 0,0:03:41.27,0:03:43.90,Default,,0000,0000,0000,,actually the maximum that\Nyou can hear or that

Dialogue: 0,0:03:45.53,0:03:49.13,Default,,0000,0000,0000,,So the audiologist raises the\Nvolume more and more, and you

Dialogue: 0,0:03:51.60,0:03:53.78,Default,,0000,0000,0000,,So what you see here\Nis the red curve.
Dialogue: 0,0:03:53.78,0:03:56.29,Default,,0000,0000,0000,,It's the level of discomfort.
Dialogue: 0,0:03:56.29,0:04:00.37,Default,,0000,0000,0000,,And also the typical thing is\Nthat it raises exactly at the

Dialogue: 0,0:04:02.87,0:04:06.11,Default,,0000,0000,0000,,This is a very complicated thing\Nfor tuning aids because
Dialogue: 0,0:04:06.11,0:04:09.61,Default,,0000,0000,0000,,they can not just amplify\Neverything.
Dialogue: 0,0:04:09.61,0:04:14.83,Default,,0000,0000,0000,,Because you would hurt people\Nvery soon, as soon as you get

Dialogue: 0,0:04:23.56,0:04:26.57,Default,,0000,0000,0000,,Actually, that's the technical\Nterm for it.
Dialogue: 0,0:04:26.57,0:04:30.71,Default,,0000,0000,0000,,It will rise, of course,\Naccording to the language and
Dialogue: 0,0:04:30.71,0:04:31.79,Default,,0000,0000,0000,,the speaker.
Dialogue: 0,0:04:31.79,0:04:33.97,Default,,0000,0000,0000,,For example, female speakers\Nhave a little slightly
Dialogue: 0,0:04:33.97,0:04:37.74,Default,,0000,0000,0000,,different curve than\Nmale speakers.
Dialogue: 0,0:04:37.74,0:04:44.03,Default,,0000,0000,0000,,And this is the area where\Nhearing aids target, which is
Dialogue: 0,0:04:44.03,0:04:47.65,Default,,0000,0000,0000,,they are used to make you\Nunderstand speech again.
Dialogue: 0,0:04:47.65,0:04:49.83,Default,,0000,0000,0000,,So they focus on this\Narea, actually.
Dialogue: 0,0:04:49.83,0:04:52.29,Default,,0000,0000,0000,,And you can see the\Nblue line here.
Dialogue: 0,0:04:52.29,0:04:54.96,Default,,0000,0000,0000,,So half of the banana\Nis actually cut.
