A healthy studio environment

As voiceover artists, we face the eternal struggle of mitigating background noise which in turn leads to working long hours in what is essentially an unhealthy environment.  I’ve had an air quality monitor on my desk or in the booth for a few years now and it acts as a useful reminder to take a break and get some fresh air!

We often focus on the technical aspects of audio recording, like microphones, software, and acoustics. But what about the air itself? It’s easy to overlook, yet the quality of the air in your studio or vocal booth directly impacts your recordings and your health.

One crucial factor is carbon dioxide (CO2) levels. While we exhale CO2 as a natural part of respiration, elevated levels can lead to a range of problems:

For all Vocalists:

• Reduced cognitive function: Higher CO2 concentrations can impair concentration, affecting a voiceover’s ability to focus on timing, emotional connection and even getting the words out in the right order! This can lead to more takes and increased fatigue.
• Vocal strain: Increased CO2 can cause inflammation and dryness in the vocal cords, making singing more difficult and potentially leading to vocal fatigue or even damage.
• Headaches and dizziness: These common symptoms of poor air quality can disrupt recording sessions and affect performance.

For Everyone in the Studio:

• Fatigue and drowsiness: High CO2 levels can make everyone in the studio feel sluggish and tired, hindering creativity and productivity.
• Long-term health concerns: Prolonged exposure to elevated CO2 can contribute to respiratory problems and other health issues.

Why Studios and Vocal Booths are Particularly Vulnerable:

• Enclosed spaces: Studios and vocal booths are often small and poorly ventilated, leading to a buildup of CO2.
• Multiple occupants: Having multiple people in a confined space further increases CO2 levels.
• Long sessions: Recording sessions can last for hours, exacerbating the problem of CO2 buildup.

Improving Air Quality:

• Ventilation: Ensure adequate ventilation by opening windows, using exhaust fans, or installing a dedicated ventilation system.
• CO2 monitors: Use a CO2 monitor to track levels in real-time and take action when necessary.
• Air purifiers: Air purifiers with HEPA filters can remove dust, pollen, and other airborne particles that can affect vocal health.
• Plants: Adding plants to your studio can help absorb CO2 and improve air quality.
• Breaks: Take regular breaks to allow fresh air to circulate and CO2 levels to decrease.

By prioritising air quality in your studio or vocal booth, you’re not just creating a healthier environment, you’re also ensuring optimal vocal performance and maximising the creative potential of everyone involved.
