La présente invention concerne une technologie d'inspection de champ sonore et, plus spécifiquement, un système d'inspection de champ sonore présentant une structure appropriée pour une petite cabine d'insonorisation par génération d'une tonalité vocale ou pure à l'aide d'un petit haut-parleur à une distance proche, réduisant ainsi une influence du bruit ambiant, et maintenant avec précision une distance entre une oreille à mesurer et le haut-parleur, ce qui permet d'obtenir des informations de test auditif plus précises; et une petite cabine d'insonorisation comprenant le système.
