Theory of Boundary Microphones and the Sanken Solution

 
There are at least two paths of sound waves from a sound source to a microphone. One is a direct route from the sound source (D1), while another is sound reflected off the floor between the sound source and the microphone (R1). Obviously, sound D1 reaches the microphone earlier than sound R1. As a result, sound waves through the R1 route have a “time delay.” The sound waves through D1 and the “delayed” sound wave (R1) will be combined at the microphone. In this case, the delay of mid and low frequencies will not be as affected because of the wavelength. In the case of high frequencies, the time delay between D1 and R1 is critical because of its short wave length. In the high frequency range, the time delay of two sound waves creates a cancellation between the two. This is known as “comb filtering.”

When we think about this phenomenon as rms sound energy, we can see energy in the high frequency range decreasing considerably when compared to the mid and low frequencies. As frequency increases, energy decreases.

When we place a microphone “on the floor,” with virtually no distance between the microphone transducer and the reflecting floor surface, most of the sound waves from the sound source to the microphone act as one direct route. Theoretically, there is no reflected route, and in this type of mic positioning, there is no time delay and, therefore, no comb filtering even in the high frequency range. This means that sound energy in the high frequencies is identical with the mid and lows. This is the basic theory of a boundary microphone.

 

A Totally New Concept in Cardioid Boundary Microphones

 
With the CUB-01 it is now possible to capture a full bodied and clear sound. Narration and dialogue are clearly caught while excluding unnecessary background noise. Sanken’s revolutionary design has also eliminated the artificial need to overdesign the acoustic construction to create cardioid directivity.

Engineered for use in many situations, from TV and film field shooting to broadcast studio production and conference table recording, the CUB-01 departs from the common design of the boundary mic, which typically requires a large, heavy plate. By comparison, the CUB-01 is unbelievably small (32mm diameter, 12mm height, 45g weight) and light.

Because of its size, it is easy to conceal from the camera, and can be positioned in a variety of environments – for example, attached to the ceiling of a car with two-sided sticky tape. The CUB-01 is available in gray or beige and in two versions – the standard high performance CUB-01 which runs on 48 volt phantom and the CUB-01-PT (pigtail) version. The PT version will operate on 3 to 10 VDC for wireless applications.
