What is a hygrometer and what does it do?

Do you know how it feels to be in a dry desert? Now compare that with what you feel when it’s hot and you are in a tropical rainforest. Can you feel the difference? While both can make you feel warm or hot, they are different from each other because of how much humidity is present.

The amount of water vapor in the air can be measured by using a hygrometer. When it is used at home, it can be connected to humidifiers or dehumidifiers to positively affect your health.

The hygrometer

In order to determine how much humidity is in the air, a hygrometer is used. This is a weather device that determines how much water is in the air. Although it plays a great role in weather forecasting, it’s function is not limited there. It also provides useful information to gardeners with greenhouses, people who have saunas, musicians who own fine stringed instruments such as violins and guitars, and as a precaution for home owners who worry about mold.

How does a hygrometer measure humidity?

Plants usually react to the humidity in the air but it may take time for them to do so. There are different types of hygrometers, and the most commonly used are the mechanical hygrometer, psychrometer, and electronic hygrometer.

Mechanical hygrometers

Mechanical hygrometers usually use a piece of twisted fibers that reacts well with humidity. Animal or plant fibers can be used, and it is twisted tightly. When there is low humidity, the fibers tighten the twist. On the other hand, when it is more humid, the twist loosens up.

The piece of fiber can be connected to a spring or needle that identifies whether the air is humid or not. Some mechanical hygrometers such as the “weather house” features a man with an umbrella and woman that comes out of a door depending on the humidity. When it is humid, the man comes out, and when it is dry, the woman comes out.

Psychrometers

Developing the psychrometer is one of the first steps in making the measurement of humidity more detailed by giving a specific number. This kind of hygrometer is also known as the wet- and dry-bulb thermometer.

Like the name implies, it makes uses of 2 thermometers. The bulb of one of the thermometers is exposed to the air while the other one is covered with a wet towel. The dry thermometer measures room temperature while the wet one shows a lower temperature because of the wet cloth that causes evaporation and cooling.

The temperature and the humidity both affects the evaporation of the wet cloth and the reading of the second thermometer. The two readings are compared and the difference between the two is known as relative humidity.

Electronic hygrometers

With technology, advancement in hygrometers can also be seen. The electronic hygrometers of today don’t directly measure the humidity, but the resistance or capacitance of instruments exposed to air; they then use that to compute for the humidity.

The capacitance is measured by using of two metal plates. There is an increase in the capacitance of the plates when the air in between the two plates has much water in it.

Similarly, a ceramic material can also be used to determine the humidity through a resistive sensor. When there is much humidity in the air, there is more water vapor that condenses inside the ceramic. The larger amount of water affects the resistance and it is measured to determine the humidity.

Hygrometer apps

In a world where you can do most things with your smartphone, it is not a surprise that there is also an app for determining humidity. The app only works when your phone has a built-in humidity sensor or you can always plug a sensor in through a USB cable.

Some apps don’t necessarily need your phone to be connected to a sensor because it gets the humidity results from a weather station. In order to do this, it first needs to figure out your location. This is why you need your GPS enabled and a connection to the internet for you to use them.

Hygrometers at home

Hygrometers made for home use may have alarms to make sure that the humidity level of your home is just right. They may also be connected to dehumidifiers or humidifiers to make sure that the humidity is kept in the right level.

When your home is too humid, it is very likely for mold and mildew to grow. Mold is related to several health illnesses and it can also cause damage to your property. Too low or too high humidity can also directly affect the health of those living in your home.

Conclusion

Hygrometers are handy tools that can be used to know how much water vapor is in the air, or how humid it is. There are different types of hygrometers, but the most technologically advanced ones are the electronic hygrometers. These can be used in your home to check the humidity for your health’s sake.

Some of us may not be very well informed about the different terms used in relation to classical music. One of the terms that many people find confusing is “philharmonic.” Through this article, you’ll learn what it means and also get to know other terms that are related to it.

Meaning of philharmonic

The term philharmonic is a combination of the two Greek words “philos” and “harmonikos.” In Italian, it is known as “filarmonico,” while in French it is known as “philharmonique.” During the 18th century, the word “philharmonic” was derived from the French term.

The term literally means love of harmony, musical harmony that is and not the feeling of harmony. It is used as an adjective, usually to describe an orchestra. It is most commonly used by various music societies all over the world to name their professional orchestra.

Other Terms Related to Philharmonic

Orchestra

This term is a general term that is used for an ensemble which plays various stringed musical instruments, woodwind instruments, percussion, brass and many others. Although they are quite famous for playing classical music, they can also play different music genres.

Chamber orchestra

In French, the term “chamber” means room. So, if an orchestra is an ensemble which plays various musical instruments together, a chamber orchestra is a small group that play together and can fit in a room. This smaller group of people can be made of up to 50 musicians. In the past, they usually play at private halls, palace chambers or even aristocratic parlors.

Symphony orchestra

A symphony orchestra is an ensemble that comprises more than 100 players of string, woodwind, brass and percussion instruments. Although it only seems to differ with the chamber orchestra because of the number of musicians in the group, the sound that they produce is also different.

They can also play various music of different genres but shine best when they play symphonies from famous classical musicians like Brahms, Beethoven, and many others.

Philharmonic orchestra vs. symphony orchestra

One confusion about the term philharmonic can be related to a philharmonic orchestra vs. a symphony orchestra. Essentially, both are the same. Both philharmonic and symphony describe the orchestra and they describe them in the same manner.

Although symphony and philharmonic have the same meaning, it isn’t right to use the terms interchangeably when you are taking about the names of the orchestras. For a large city such as London or New York, it is possible that there is more than one professional orchestra.

One may be named the London Philharmonic Orchestra, and the other the London Symphony Orchestra. The two are different orchestras but they can play the same music and they also have more than 100 different musicians.

Your first philharmonic or symphony orchestra concert

Classical music isn’t really new to hear, even if you consider yourself a person who loves the more modern genre. We can hear classical music every day, or at least part of it. Many pieces familiar to us because we have heard them in movie soundtracks, cartoons, elevators and even retail shops. Some of the popular music of today even incorporate the classical melodies too.

There is really something beautiful with the music played by a full orchestra. They are enjoyable to watch and hear live. If it is your first time to experience a live orchestra performance, there are a few things that you should know.

The best way to enjoy the concert is simply to let yourself open up to the music. Feel it and just enjoy it. Some things may seem weird or new to you, but the best thing to do is to focus on the music.

It is best to arrive early so that you can settle in your seat and browse through the program. It is also great to watch the orchestra warm up for the concert.

Most of the time, there is a break in the middle of the concert to give the musicians time to rest and the audience time to eat, mingle with friends or use the bathroom.

Clapping is done during the beginning of the show as a welcome sign for the conductor and all the musicians. The audience doesn’t usually clap in the middle of the piece but waits until the end of the piece.

Recording the concert by making use of any device is not allowed.
