What is 'white sound' primarily used for?

1. To enhance visual appeal in a space

2. To provide speech privacy and mask noise

3. To improve the temperature of a room

4. To block all ambient noise

The correct answer is: To provide speech privacy and mask noise

White sound is primarily used to provide speech privacy and mask noise. This type of sound consists of a consistent noise spectrum that is effective in reducing the perceived levels of ambient noise in a space. By adding white noise to an environment, it helps to mask disruptive sounds, allowing for more privacy during conversations and reducing distractions. This is particularly useful in open office environments, waiting rooms, or any space where conversations need to be kept confidential or where ambient noise may interfere with focus. The use of white noise does not pertain to enhancing visual appeal, improving temperature, or completely blocking ambient noise. Instead, it offers a masking effect that can help create a more comfortable auditory environment, thus promoting better concentration and privacy without the need for visual alterations or temperature control.
