A throat microphone, also called a laryngophone, is a type of contact microphone that absorbs vibrations directly from the wearer's throat by way of single or dual sensors worn against the neck. The sensors, called transducers, can pick up speech even in extremely noisy or windy environments, such as on a motorcycle or in a nightclub. Other types of microphones do not function well under these conditions because of high levels of background noise. Advanced laryngophones are able to pick up whispers, and therefore perform well in environments where communicating with others at a distance in silence is required, such as during covert military or law enforcement operations. Throat microphones are also very useful when helmets or respiratory protection is required. Many full-face SCBA, CABA, SAR respirator, PAPR, or re-breather masks do not have a provision for a microphone inside the mask. The throat microphone can be used safely, as it is positioned outside the mask's face seal and as such does not compromise the respiratory protection provided by the mask, nor does it violate mask approvals and certification.

After undergoing surgery for partial or total laryngectomy due to throat cancer or accidental damage to the larynx, with the consequent removal of the vocal cords, one is no longer able to speak. This condition is due to the absence of vibrations which were previously produced by the vocal cords. To overcome this challenge, there is no solution other than to artificially produce these vibrations. The ROMET® Electronic Larynx or Electrolarynx, produces such vibrations and permits the user to emit clear and very comprehensible vocal sounds.

Amplicord has been producing and distributing voice prosthesis speech aids since 1975. Our electrolarinxes are Class I, non invasive medical devices that allow patients whom have undergone larynx surgeries and vocal chords asportation to communicate vocally.

The mass production of the Electrolarynx and its distribution, both in Italy and abroad, began in the early days of the company, using mechanical components for manufacturing processes.

The electrolarynx: voice restoration after total laryngectomy

The ability to speak and communicate with one’s voice is a unique human characteristic and is fundamental to many activities of daily living, such as talking on the phone and speaking to loved ones. When the larynx is removed during a total laryngectomy (TL), loss of voice can lead to a devastating decrease in a patient’s quality of life, and precipitate significant frustration over their inability to communicate with others effectively.
