(Main)Underwater Acoustics - Calibration of acoustic wave vector receivers in the frequency range 5 Hz to 10 kHz (IEC 63305:2024)
Underwater Acoustics - Calibration of acoustic wave vector receivers in the frequency range 5 Hz to 10 kHz (IEC 63305:2024)
IEC 63305:2024 specifies methods and procedures for calibration of vector receivers in the frequency range 5 Hz to 10 kHz, which are applicable to vector receivers based on the two different principles. In addition, it describes an absolute method of inertial vector receiver calibration in air using optical interferometry.
Usually, acoustic wave vector receivers are designed and constructed based on one of two principles. One is the sound pressure difference (gradient) principle. When measuring with this sensor, the vector receiver is rigidly fixed on a mount and supported in water. The other is the co-vibrating (inertial) principle. When measuring with this sensor, the vector receiver is suspended on a mount and supported in water in a non-rigid manner, which allows the vector receiver co-vibrate in the same direction as the sound particle in the sound wave field.
Many methods have been used to calibrate vector receivers, such as free-field calibration, calibration in standing wave tube and calibration in a travelling wave tube.

Acoustique sous-marine - Étalonnage des récepteurs vectoriels d’ondes acoustiques dans la plage de fréquences de 5 Hz à 10 kHz (IEC 63305:2024)
L'IEC 63305:2024 spécifie les méthodes et procédures d’étalonnage des récepteurs vectoriels dans la plage de fréquences de 5 Hz à 10 kHz, qui sont applicables aux récepteurs vectoriels sur la base de deux principes différents. En outre, il décrit une méthode absolue d’étalonnage des récepteurs vectoriels inertiels dans l’air à l’aide de l’interférométrie optique.
En général, les récepteurs vectoriels d’ondes acoustiques sont conçus et construits sur la base de l’un des deux principes suivants. L’un réside sur le principe de la différence de pression acoustique (gradient). Lors du mesurage avec ce capteur, le récepteur vectoriel est fixé de manière rigide sur un support et soutenu dans l'eau. L’autre principe repose sur la co-vibration (inertie). Lors du mesurage avec ce capteur, le récepteur vectoriel est suspendu à un support et soutenu dans l'eau de manière non rigide, ce qui permet une co-vibration de ce dernier dans la même direction que la particule acoustique dans le champ d'ondes acoustiques.
De nombreuses méthodes ont été appliquées pour étalonner les récepteurs vectoriels, telles que l’étalonnage en champ libre, l’étalonnage dans un tube à ondes stationnaires et l’étalonnage dans un tube à ondes progressives
Podvodna akustika - Kalibracija zvočnega vala vektorskih sprejemnikov v frekvenčnem območju od 5 Hz do 10 kHz (IEC 63305:2024)
Standard IEC 63305:2024 določa metode in postopke za kalibracijo vektorskih sprejemnikov v frekvenčnem območju od 5 Hz do 10 kHz, ki se uporabljajo za vektorske sprejemnike na podlagi dveh načel. Poleg tega opisuje absolutno metodo kalibracije inercijskega vektorskega sprejemnika v zraku z optično interferometrijo.
Vektorski sprejemniki zvočnih valov so običajno zasnovani in izdelani na podlagi enega od dveh načel. Prvo je načelo razlike v zvočnem tlaku (gradientno načelo) – pri merjenju s tem senzorjem je vektorski sprejemnik trdno pritrjen na nosilec in podprt v vodi. Drugo je kovibracijsko (inertno) načelo – pri merjenju s tem senzorjem vektorski sprejemnik visi na nosilcu in je podprt v vodi, vendar ni pritrjen, zaradi česar lahko sočasno vibrira v isti smeri kot zvočni delec v polju zvočnega vala.
Za kalibracijo vektorskih sprejemnikov so bile uporabljene številne metode, npr. kalibracija v prostem polju, kalibracija v cevi na stoječe valove in kalibracija v cevi na potujoče valove.
