Dynamic FM

Dynamic FM is Phonak’s latest and most advanced FM

platform. It has completely reshaped the face of FM technology.

Dynamic FM systems are not merely pieces of hardware

transmitting sound from one place to another. They are

masterpieces of wireless technology, capable of adapting

themselves continuously to the actual surroundings. The

most important feature of Dynamic FM is its adaptive FM

advantage. It adjusts the gain of the FM receiver, depending

on the ambient noise. The result is an incredible improvement

in speech understanding, which in noisy conditions reaches

of dozens percentage points (see picture below). Other

features are equally impressive, such as MultiTalker Network,

which allows up to 10 transmitters (inspiro or DynaMic)

to form an ad hoc network in a classroom, ensuring that

everybody can speak and everybody can hear. DataLogging

FM meanwhile provides audiologists with a comprehensive

insight into the daily usage patterns of a Dynamic FM system

in school, which can lead to better counseling of teachers and

parents.

Today Phonak offers 5 different Dynamic FM transmitters:

inspiro, DynaMic, SmartLink+, ZoomLink+ and EasyLink+.

inspiro and DynaMic are the optimal transmitters for school

environment. On the one hand these products are full of

cutting edge technology; on the other they are also very easy

to use and robust enough to withstand heavy school use.

Individual customization is child’s play, while customers also

benefit from ongoing developments at Phonak as new

features can be obtained free of charge via optional firmware

upgrades over the internet.

trans mitters of choice for teenagers and adults. SmartLink+
