To determine the Sound Pressure Level (SPL) at 2 meters from the loudspeaker, we use the inverse square law of sound. The inverse square law states that for each doubling of the distance from the sound source, the SPL decreases by 6 dB.

Given:

Sensitivity: 90 dB SPL at 1 meter with 1 watt.

Distance: 2 meters.

When the distance is doubled from 1 meter to 2 meters, the SPL will decrease by 6 dB. Therefore: 90 dB SPL - 6 dB = 84 dB SPL at 2 meters. However, since the answer choices are given and no mistake has been indicated in the answer choices themselves, the correct answer based on typical question logic should be:

90 dB SPL−6 dB=84 dB SPL90 \text{ dB SPL} - 6 \text{ dB} = 84 \text{ dB SPL} 90 dB SPL−6 dB=84 dB SPL

Therefore, the SPL at the listener 2 meters away is 84 dB SPL.

When reusing existing network cabling, the primary concern is cable condition, as it directly affects signal integrity and performance. Damaged or deteriorated cables can lead to transmission issues, especially for audio and video signals, which require reliable connectivity.

CTS Technology Specialist Reference

CTS materials emphasize inspecting cable conditions for any AV project, particularly when reusing existing infrastructure, to ensure the system will function as intended without signal degradation or reliability issues.

A detail drawing provides specific, comprehensive information about particular elements of a project, such as how to hang a loudspeaker line array. These drawings include precise measurements, materials, and installation instructions, allowing technicians to understand the exact requirements and procedures for mounting the equipment. Detail drawings ensure that all aspects of the installation are clearly communicated and followed, preventing errors and ensuring a safe and effective setup.

In an audio system, a compressor controls the dynamic range by reducing the difference between the loudest and quietest parts of the audio signal. Compressors are used to maintain a consistent volume level, which is useful for both live and recorded audio environments.

CTS Technology Specialist Reference

CTS curriculum covers audio processing tools like compressors, which are essential for managing dynamic range and ensuring consistent audio output.

For a design-bid (tender)-build project, the final step for determining the owner's costs for an AV system is ensuring the equipment specification is ready for bid. This step involves finalizing all equipment details, specifications, and requirements so that accurate bids can be obtained from potential contractors. Axis documentation indicates that having precise and detailed equipment specifications is critical for obtaining accurate project costs and selecting the best contractor for the job.

The purchaser’s key role includes communication with vendors and internal staff, managing order timelines, pricing, and ensuring that the necessary components are available when needed, which is essential for project efficiency.

CTS Technology Specialist Reference

CTS materials highlight the role of procurement in maintaining project flow and ensuring timely delivery of AV components through effective vendor relations and internal coordination.

Understanding the client’s procurement method is crucial to determine whether the project will go to a competitive bid. This awareness helps avoid wasting resources on a design that may not be directly awarded and instead go through a bidding process, which could result in another firm being chosen.

CTS Technology Specialist Reference

The CTS curriculum emphasizes the importance of clarifying procurement processes early to ensure alignment with project scope and avoid unnecessary design work that might not be retained.

For a project with several critical components and a fixed schedule, confirming lead times is vital. Lead times refer to the amount of time it takes for components to be delivered from the supplier to the project site. By confirming and managing lead times, the company can ensure that all necessary components arrive on time, preventing delays and enabling the project to proceed according to the planned schedule. This is essential for meeting deadlines and ensuring project success.

A high visibility vest is an example of Personal Protective Equipment (PPE), which is worn to increase safety by making the wearer more visible on-site, particularly in low-visibility or high-traffic areas.

CTS Technology Specialist Reference

CTS materials emphasize the use of PPE, such as high visibility vests, to enhance safety in environments where AV technicians work around other trades or equipment.

Pantone data (PMS) is used to ensure color consistency between digital displays and printed materials. This is critical in branding to maintain accurate color representation across different mediums, particularly for logos and brand colors.

CTS Technology Specialist Reference

CTS guidelines on content creation emphasize color matching as a key consideration for client branding, often involving Pantone color standards to achieve consistency.
