For contacting upper and lower workers a little away
On 2013-10-07 11:21:46
I bought it for the contact of the upper and lower workers in a slightly noisy working environment. I was in a loud voice until now, but I'll be in touch with this hand megaphone from now on. I got one each for the top and bottom so that I could contact you. It is small and it can also emit alarm sounds, which is convenient when turning attention to here. Although it will be used at the maximum volume, it is easy to cause howling. If you isolate the sound between the speaker and the microphone and change to a more directional microphone, the howling is likely to decrease. There is no use in work yet, so I'd like to write a review of durability etc when actually used.
