hi welcome to the solak cfia channel
Vision this test determines the
regularity and linearity of the
frequency response by listening at the
beginning there will be the comparison
with pink noise then with musical pieces
listen and find the between the original
reference sound and the sound of the
headphone the closer the headphone get
to the original reference sound the more
linear and regular the headphone will be
at each step the frequency response
I know you told your friend you're not
okay and tell me what's wrong and why
you never said you felt that way guess
you trying to stay strong and fake smile
and until I look away but I've known you
too long it hurts to watch your blue
eyes Fade to gray as you fade [Music]
away yeah I'm about to fade away cuz
every time I wake up I feel like it's
Monday something's going wrong with all
the chemicals up in my brain all a
sudden I don't look at anything the same
way got to build up of my thoughts
sitting in an ashtray I'm sorry that I'm
so inconvenient okay just let me be me
and I'll stay out of your way I can see
the way you look at me I'm such a
disgrace I never really asked to be
brought into this place you want to love
me well the baby out a taste all the
highs and the lows no you'll never be
the same I don't really want to hurt you
but I can't control the pain if you're
sticking by my side maybe we could be
okay okay okay maybe you could be the
change I need today I promise that I'm
never f this way I really hope that you
will choose to stay through all the pain
[Music]
this test measures the transient speed
and relative irregularity to the dur
impulse response best way to test
headphone speed and relative transient
speed all this determines the
transparency and sharpness of the
headphone if the headphone impulse graph
looks like to the reference Dura impulse
then the headphone will be fast
the scores reported are not a personal
evaluation or evaluation of experts in
the field but derived from laboratory
measurements converted by algorithms
into scores from 0 to 30 in particular
the graphs of the laboratory tests are
read Point by point and converted into
scores using algorithms all this for
ease of reading and consultation
