Windscreens and Nose cones 

Wind  induced noise can be reduced by using a  windscreen.  This  can offer some protection against dust 
particles and mechanical damage. In the presence of high-speed airflow from a well-defined direction, such 
as  wind tunnels,  a nose cone is  recommended.  When using windscreens and noise cones,  the frequency 
response of the microphone will be attenuated at higher frequencies. 

Clamps and stands 

When holding a microphone in place, it is important to minimize the influence of the stand on the sound 
being measured. This can be accomplished by using low profile stands and clamps available from PCB. 

Cables and Electronics 

PCB carries LEMO

 cables as well as coaxial cables with BNC and 10-32 connectors. Traditional exter-

nally polarized microphone power supplies along with a variety of ICP

®

 signal conditioners are available 

that will fit almost any need.

Maintenance 

Microphones are very stable over long periods of time, provided they are handled and stored properly. The 
microphone contains fragile components that can be damaged by misuse, in particular the diaphragm, which 
is made up of a very thin proprietary material and should be kept clean of dust, dirt, moisture and free any 
type of imperfection (scratch, dent, etc.). 

The microphone’s grid cap is designed to let the true sound pressure level through to the diaphragm while 
preventing items from coming in contact with it. We do not recommend that you ever remove the grid cap 
or clean the microphone. If you take the precautionary measures to keep the microphone clean and dry, it 
should not be necessary. Should you need to remove the grid cap to replace it with PCB’s enhanced rugged 
grid cap (shown below, and as an independent part of a rugged kit) to extend the lifespan of the precision 
measuring device, caution should be taken to ensure the delicate diaphragm sensing element remains un-
touched and safe.  

   

     

 

Use of accessories, like windscreens, and desiccants will help keep moisture off the microphone and main-
tain the specified sensitivity level. Nose cones will help keep turbulence off the microphone diaphragm and 
allow the sound pressure to be measured with greater accuracy. 

Keep the microphone and preamplifier assembled while preparing for testing. Keep the rubber maintenance 
caps on the preamplifier’s electrical connector only. Do not place these rubber caps over the microphone. 
This  will  create  a  vacuum  and  undo  pressure  on  the  microphone  diaphragm,  which  can  stretch  the  dia-
phragm and cause a change in sensitivity. Store the microphones and preamplifiers in their protective cases 
when not in use.  

Dust,  rain,  oil,  moisture  or  exposure  to  extreme  temperatures  may  adversely  affect  the  microphone  and 
preamplifier’s performance. If the microphone or the inside of the connection area of the preamplifier be-
comes contaminated, use a light pressure rubber bulb to gently blow clean, dry air onto the unit in order to 
remove  the  dust.  In  the  event  that  you  absolutely  must  take  off  the  grid  cap  and  clean  the  microphone 
diaphragm,  we recommend using a blow bulb  or  a  light  pressure,  clean and dry air hose to  gently  blow 
contamination off the diaphragm. The direction of the air should be parallel with the diaphragm, not directly 
(0 degree incidence) pointed at the diaphragm. Do not touch the microphone’s diaphragm with your fingers 
or let it come in contact with any sharp or pointed object. Please note that any contact to the microphone’s 
diaphragm can negatively impact the sensitivity and long term stability of the microphone.
