Hello to Everyone !
I have a very basic question
Can a felt be too thick to cause a dip in the frequency response of an headphone like the one present here just above the 10kHz ?
Or the effect of a felt is measurable only in fraction of dB of attenuation ?
Could the FR without the felt be flatter in the range 10 to 20 kHz ?
Personally I am worried by felts after hearing sensible improvements in sound every time I have removed them.
Thanks and kind regards,
P.S. just some readings
Since the effectiveness of vibration/sound absorption increases with frequency, it can be assumed that, as felt is effective at very low frequencies, it is even more effective at higher frequencies.
Any time I remove it I heard a better sound. Any.
