I've read this doc article and I've tried using the fdesign.octave-design duo, but this method allows creation of band filters for mid-band frequencies starting at around 25Hz. I need to create filters for frequency range from 0.5Hz to 100Hz.

WebMany young adults engage in loud activities, which can cause noise-induced hearing loss (NIHL). Some studies suggest that NIHL and age-related hearing loss (ARHL) lead to relatively rapid shifts in the hearing threshold level (HTL) of the extended high frequency (EHF) range (> 8 kHz). It has been hypothesised that NIHL may first present with HTL … WebI have this problem big time. There are 2 components to it. (1) What is the overall range of vocal frequencies you are trying to sing? For instance for me, I only have about an octave and a 1/2 of a singing range therefore it doesn't matter what key I play in, if I try to have a song that the vocal melody spans more than an octave and a 1/2 I won't be able to sing …
