Sound Levels

The term “Soundproof” can be confusing in reference to nearly any real life product or space, including Meeting Pods. Due the widespread use of this terminology, we wanted to clearly define the meaning of Soundproof in the context of LaunchPod products.

The Meaning of SoundProof

The typical reference point for Meeting Pods labelled as “Soundproof” currently on the market is a 30dB reduction of the sound level in the typical range of human speech.

The range of frequencies for the human voice is not necessarily what one might expect, with a male speaking voice fundamental tones being between 85Hz and 155Hz and female between 155Hz and 255Hz. In fact, the highest note of a female Soprano is only 1280Hz. On this basis, a Meeting Pod only needs to focus on a narrow range of frequencies, unless being used for music or other purposes.

LaunchPod’s Meeting Pods achieve a result in these ranges up to around 35dB (as shown by graph on left for sPod testing), but generally over 30dB reduction.

This 30dB+ level of reduction is quite significant and generally is perfectly acceptable for reducing intelligibility of speech inside the Pod to low levels, however the ability to discern conversations is more complex than a simple sound level reduction for a Pod. The ambient sound level of the office is a key factor, as well as the intended use of the Pod.

Your business may need a Meeting Pod to reduce the ability to hear and discern conversations inside the Pod, but perhaps you need the occupants of the Pod to not hear what is going on outside the Pod, or perhaps you need to isolate a vocalist from the band for recording purposes? Our clients have a vast number of different reasons for choosing LaunchPod to solve these critical issues in their environment.

Why is Ambient Sound Critical?

Have you ever been working in a totally silent environment (an exam for instance) and suddenly a car horn from 3 blocks away grabs your attention, stopping you getting back to the task at hand for a few minutes?

The human brain can sometimes operate out of our conscious control, and we find ourselves focusing on the thread of a nearby conversation, even though we can barely hear the words.

Science shows that in the new workplace environment, the “One Sided” Conversations (ie headphones) are even worse, as our brains work hard to decipher what the conversation is about.

In contrast to the belief that a totally silent office is the most productive, numerous studies have proven that “White Noise” can be used in any environment to provide a pleasing masking effect which achieves the following benefits:

  • Reduces distraction from unexpected sounds, eliminating the need to refocus constantly;
  • Eliminates the ability for the brain to focus on surrounding conversations – they all blend into the noise;
  • Makes it impossible to discern any conversations nearby;
  • Provides a relaxing backdrop to improve concentration and even increase creativity.

The use of carefully managed ambient noise works brilliantly with Soundproof Meeting Pods to provide the highest level of privacy and a highly productive environment for staff.
