The vocal apparatus
Voice production takes place in the larynx, which contains the vocal folds and vocal cords surrounded by a mucous membrane.
Benefits
Controlled humidity in call centres protects health, reduces absenteeism and fatigue, and reduces voice problems. At the same time, sensitive IT equipment and electronics are protected from electrostatic discharge.
Less respiratory infections
Additional air humidification reduces the spread of viruses and boosts the immune system.
Prevent voice problems
A minimum humidity of 40% protects the vocal apparatus from strain and improves the quality of conversation.
Refreshing indoor climate
Evaporative cooling of air creates a revitalising and refreshing indoor climate.
Humidity control for call centres
Air humidification for better health and performance
In call and service centres, the voice is the most important tool. High call quality and successful customer dialogue depend on a natural voice. Additional air humidification lays the foundation for a healthy working environment. Controlled air humidity protects against voice strain, reduces the spread of viruses and boosts the immune system. Studies show that optimal air humidity reduces the survival rate of viruses by a factor of 3. It also protects the tear film of the eyes and prevents inflammation, infection and irritation. At the same time, concentration and performance are improved: revitalising air humidity increases well-being, which has a positive effect on employee motivation and productivity. In voice-intensive working environments such as call centres, air humidification is therefore a decisive factor for health and performance.
Natural cooling for greater comfort
Evaporative cooling uses the evaporation of fine aerosols from additional air humidification to lower the temperature and create a pleasant, refreshing indoor climate. Thermal comfort is particularly important in call and service centres, where employees work intensively and talk for hours on end. Workplaces that are too warm can severely impair performance and reduce concentration. Evaporative cooling counteracts this by lowering the air temperature and simultaneously increasing the humidity – a benefit for the voice and respiratory tract. Unlike conventional cooling systems, the principle of evaporative cooling is energy-efficient and environmentally friendly. It creates a fresh, natural indoor atmosphere that increases well-being and promotes productivity.
Prevent damage to sensitive equipment
Maintaining optimal humidity in call centres is not only important for employee comfort and health but also crucial to protect sensitive electronic equipment. Low humidity can lead to electrostatic discharges that damage headsets, servers, and other technical devices, while excessive humidity increases the risk of corrosion and malfunction. By keeping the air humidity at the right balance, call centres ensure stable operation of their critical IT and telecommunication systems. This creates a safer environment for both people and technology, reducing costly downtime and equipment replacement. At the same time, controlled humidity improves voice clarity and employee well-being, leading to healthier staff and higher service quality. Investing in humidity control therefore safeguards valuable equipment, prolongs its lifespan, and ensures reliable and efficient operations in the call centre.
The respiratory tract
A relative humidity of between 40 and 60% protects the respiratory tract from infections caused by viruses and other pathogens. This allows the self-cleaning function of the mucous membranes to work optimally.
The vocal folds
If the air is too dry, the vocal folds lose their optimal moisture and elasticity. The glottis no longer closes completely. Side air enters the vocal apparatus. Voice problems arise.
The glottis
When the air is too dry, the glottis is no longer completely closed by the vocal folds. The intrusion of secondary air causes coughing, throat clearing and voice problems.
The vocal cords
The vocal cords require optimal humidity to enable the voice to function healthily and produce a clear sound.
Use cases
In call centres, optimum humidity protects against voice problems and respiratory infections, strengthens the immune system and ensures a refreshing indoor climate thanks to evaporative cooling.
Humidification boosts the immune system
Controlled humidity in buildings protects the self-cleaning function of the mucous membranes, reduces the risk of infection and strengthens the immune system. Dry air promotes respiratory diseases. Additional humidification ensures healthy indoor air and strengthens the immune system.
Humidity protects against dry eyes
Controlled humidity protects against dry eyes, eye irritation, burning and redness, and prevents strain during intensive computer work.
Healthy skin with optimal humidity
Symptoms and causes of dry skin, and tips for healthy skin through optimal humidity.
Humidity reduces respiratory infections
Optimal humidity reduces the risk of respiratory infections, shortens the lifespan of viruses, inhibits the spread of infectious viruses through the air and protects against colds, flu and COVID-19.
Healthy voice with optimal humidity
Optimal humidity protects the voice from strain, hoarseness and vocal problems. This is an important factor for better health and well-being – for example, in call centres, concert halls, opera houses or customer service departments, where the voice is put under a lot of strain and the quality of conversation is important.
