Acoustic engineering mostly needs cochlear knowledge, but spatial audio relies on SOC function

Evidence

As the neuronal processes in the cochlea are only partly understood, it is quite understandable that the knowledge of neural processes beyond the cochlea is even more sparse. However, for acoustic engineering applications, understanding the functioning of the cochlea is usually enough, although certain spatial audio reproduction methods rely on knowledge of the function of the nuclei in the SOC. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 811
