deltasoner
A deltasoner is a class of precision acoustic measurement device designed to detect and analyze sub-harmonic
The concept of the deltasoner emerged in the early 2010s as researchers sought more sensitive tools for
Technically, a deltasoner comprises a sensor array, an analog‑to‑digital conversion chain, and a processing unit that
Applications of deltasoners span aerospace, civil engineering, and acoustic research. In aerospace, they monitor the integrity
