Provided it’s loud enough, people outside the room won’t be able to hear your conversation. Using a white noise machine for office privacy helps to mask the sound of conversation in essentially the opposite way to the benefit described above. It found that white noise helps memory retention and improves learning in loud environments.īoth of these factors are necessary for improved productivity, so the link should be obvious.įinally, another important factor is privacy. In 2014, the Journal of Cognitive Neuroscience published a study on this subject. Similarly, white noise is shown to help productivity. This helps with concentration but also with relaxation, which is why it’s useful in therapy offices. Playing every audible frequency not only masks existing noise pollution, but also gives your brain something indeterminate to focus on. So why does white noise help in situations such as offices or therapy? The main reason is that white noise “confuses” your brain and helps to block out distracting background noise. White Noise and Productivity in an Office, Cubicles, or in Therapy So, when it comes to choosing a white noise machine for office cubicles, you obviously need to ensure it’s louder than 50dB. Here’s a chart of some common sounds in decibels. Decibels are logarithmic, which means that every 10dB increase results in a doubling of perceived loudness. We measure amplitude in decibels (dB), which refers to the sound wave’s pressure level (intensity). Various other factors impact volume, but amplitude is the main one. As mentioned, humans can typically hear between 20Hz (low frequency) and 20kHz (high frequency).Īmplitude refers to a wave’s strength, which we typically perceive as its volume (or loudness). We measure frequency in Hertz (Hz) and a high-frequency wave oscillates more than a low-frequency wave within a set duration. This means they move back and forth in a regular, repetitive way. Sound waves are, unsurprisingly, waves that oscillate. These are common terms when discussing sound, but it’ll help to define them so we can understand how white noise machines work.įrequency (also known as pitch) is the number of times per second that a sound wave repeats itself. Frequency and Amplitude in White Noise Machines for Office CubiclesĪbove I used the terms frequency and amplitude.
