摘要:
The invention relates to an output reducing system for a telephone system, e.g. implemented in a headset, comprising an input line and an output line, where the input line is transmitting an incoming signal to an output transducer and where the output line in transmitting an outgoing signal from an input transducer, where it connection with the input line a compressor system is provided for reducing the output signal level.

The present disclosure is directed to a metal-containing apparatus including a substrate member constructed of a metal that is highly resistant to pitting corrosion and wear in aggressive media. An exemplary metal-containing apparatus is a plate heat exchanger. The metal includes an oxidation layer on the surface thereof and a thin metal oxide nanoporous film on top of the oxidation layer. The nanoporous film is highly compliant and is comprised of oxygen and aluminum, titanium, silicon, zirconium and combinations thereof.
