Microphone hygiene in covid times

The covid pandemic has changed our practices a lot, especially regarding hygiene.. We have understood the importance of cleaning and disinfecting.

Although we are already used to the protocols for cleaning hands and face masks, scientists have discovered that the covid 19 virus can remain on surfaces and onjects for a long time. 

Microphones during covid

Microphones are objects that are frequently shared by different individuals therefore it is extremely important to keep them clean.

The best solution is to maintain a thorough disinfection routine to prevent any contagion, not just covid-19, and to keep users safe. Microphones have a complex shaped surface that can harbor many germs if they are not disinfectedproperly and regularly.

How to clean microphones and keep them disinfected 

Using materials such as soap, alcohol, water or another disinfectant product can damage not only the physical appearance of the microphones but also the internal functioning. This is definitely not what audio engineers and technicians  want to happen to their equipment. The safest way to disinfect a microphone is to use Li.LAC. The UV-C light-based disinfection is fast, safe and easy to use.

At Li.LAC, we have done many tests to evaluate the impact of UV-C light and the results have shown that the aging effect implied by UV-C disinfection inside Li. LAC is negligible compared to the normal aging that happens to the microphones (by mechanical impacts, dirt, humidity etc.).

The UV-C cycle takes only 5 to 10 minutes. 

What is UV-C light? 

Ultraviolet germicidal irradiation is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.

UV-C light is considered germicidal UV because of its wavelengths between 200 nm and 300 nm are strongly absorbed by nucleic acids. According to laboratory test results, bacteria and viruses are inactivated by99.99% on the surface of an object after 5 minutes of irradiation inside Li.LAC.

The steel grille inside the Li.LAC’s irradiation chamber is optimized to accommodate up to three handheld microphones or handheld transmitters. The uv-c energy distribution inside Li.LAC is purposely inhomogeneous: The microphone head (with metal grille and inner foam) receives a higher irradiation than the shaft. This is important in order to guarantee a good disinfection without wearing out UV-C sensitive plastic parts like for example the acrylic display glass on a handheld transmitter.

It is important to understand that any kind of shadowing effect (for example, by putting too many items into the chamber) will reduce the effectiveness of the disinfection.
