WALETS LOVER SOUND SYSTEM & SOUND LEVEL METER 分貝表

THE  WALETS LOVER SOUND SYSTEM :-  Fekuensi Khusus Memanggil Burung Walet 

This is a special Swiftlets Lover Sound System. It incorporates a Mp3 player with special frequencies to attract swiftlets.

These sound systems are similar to the regular Mp3 players which we use in the bird house. The sound level meter is used to measure the decibel (dB) of the sound frequency. (The decibel is a measure of sound pressue level)

Through these accurate measurements, we can optimise the sounds which are used in the swiftlet house. Different decibels can have different effects on the swiftlets attracted to the birdhouse.

With a little effort and time spent in making the measurements, this device will help the bird house owner analyse the data and use the optimum decibel levels for swftlets sounds, therefore making the swiftlet house a success.

分貝dB(decibel)是量度兩個相同單位之數量比例的單位,主要用於度声音強度,常用dB表示。「分」(deci-)指十分之一,個位是「貝」(bel),但一般只採用分貝。
