Hearing aids -- Part 4: Magnetic field strength in audio-frequency induction loops for hearing aid purposes

Applies to audio-frequency induction loop systems producing an alternating magnetic field and intended to provide an input signal for hearing aids operating with an induction pick-up coil. Specifies a standard value of magnetic field strength in audio-frequency induction loops for hearing aid purposes, such as will give an adequate signal-to-noise ratio without overloading the hearing aid.

Appareils de correction auditive -- Partie 4: Intensité du champ magnétique dans les boucles d'induction audiofréquences utilisées à des fins de correction auditive

S'applique aux systèmes à boucles d'induction audiofréquences qui produisent un champ magnétique alternatif et qui sont destinés à fournir un signal d'entrée pour les appareils de correction auditive fonctionnant avec une bobine d'induction captrice. Spécifie une valeur normalisée d'intensité de champ magnétique dans les boucles d'induction audiofréquences destinées à des fins de correction auditive, de manière à obtenir un rapport signal sur bruit convenable, sans surcharger l'appareil de correction auditive.
