Which microphone type has a basic cardioid pick up pattern?
A cardioid microphone has a heart-shaped (or ''cardioid'') pick-up pattern that captures sound primarily from the front while rejecting sound from the rear. The pattern shown for Type(b) aligns with a typical cardioid response, featuring a coverage angle of approximately 131, which indicates its directional sensitivity towards the front and rejection from the back.

In the scope of work (SOW), an interface is described as being installed in the lectern. While the work is underway onsite, the client asks for the interface to be moved to a table next to the lectern. What is the proper response from the technician?
If a client requests a change to the scope of work, such as relocating equipment, the technician should advise the project manager. This ensures that the request is documented and assessed for impact on the project scope, budget, and timeline, maintaining proper project management protocols.
CTS Technology Specialist Reference According to CTS standards, scope changes should be communicated to project management to ensure appropriate adjustments and approvals are made.
A client with an open concept office space has stated a concern regarding speech privacy for workers. A possible solution for this issue is a(n)
For an open-concept office space where speech privacy is a concern, a sound masking system is an effective solution. Sound masking involves adding a background sound, usually similar to airflow, to reduce the intelligibility of speech. This helps in minimizing distractions and enhancing privacy without isolating individuals physically.
CTS Technology Specialist Reference The CTS materials highlight sound masking as a preferred solution for enhancing speech privacy in open office environments. It effectively addresses concerns related to audible distractions and speech privacy, making it well-suited for such spaces.

This image shows the workings of which type of microphone?
The image shows a dynamic microphone, which works through electromagnetic induction. In a dynamic microphone, sound waves cause the diaphragm to move, which in turn moves a coil of wire within the magnetic field of a magnet. This movement generates an electrical signal that corresponds to the sound. The visible components, such as the diaphragm, coil, and magnet, are characteristic of a dynamic microphone's internal structure.
CTS Technology Specialist Reference The CTS curriculum details the workings of various microphone types, explaining that dynamic microphones are durable and suitable for live sound due to their ability to handle high sound pressure levels.
