An Entity of Type: Vehicle104524313, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Ultrasound can be modulated to carry an audio signal (like radio signals are modulated). This is often used to carry messages underwater, in underwater diving communicators, and short-range (under five miles) communication with submarines; the received ultrasound signal is decoded into audible sound by a modulated-ultrasound receiver. A modulated ultrasound receiver is a device that receives a modulated ultrasound signal and decodes it for use as sound, navigational-position information, etc. Its function is somewhat like that of a radio receiver.

  • يمكن أن يتم تعديل الموجات فوق الصوتية لتحمل إشارة صوتية (كتعديل الإشارات اللاسلكية). ويتم استخدام هذا الأمر في كثير من الأحيان لتمرير الرسائل تحت الماء، من أجل التواصل بين غواصين تحت الماء، وللتواصل تحت أعماق قصيرة (خمسة أميال) بين الغواصات؛ يتم فك شفرات إشارة الموجات فوق الصوتية إلى صوت مسموع بواسطة مستقبل الموجات فوق الصوتية المعدلة.
