Sound waves and frequency problem

In summary, a study is being conducted on the factors that affect the audibility of sound in school assemblies using a public-address system. The initial objective of investigating the relationship between frequency and tension, length, and material of a string was rejected, as was the objective of studying the relationship between amplitude, frequency, and loudness of sound. The speaker suggests other factors to consider, such as the quality of the PA system, the proximity of the speaker to the microphone, and external influences like wind and temperature.

Homework Statement


A public-address system is usually used in the school assembly to obtain better attention from students. Carry out a study on the factors affecting the audibility of sound.

Homework Equations

The Attempt at a Solution


Objective: To study how does the frequency of the sound are affected by tension, length and material of the string. This objective was rejected by teacher. I had come up another objective which is to investigate the relationship between the amplitude and frequency and the loudness of sound was also rejected. Any other suggestions regarding this topic?[/B]

It seems that you need to investigate what has an influence
on how well the students can hear the messages over the PA system.
That would be the PA system itself, maybe how well it reproduces various
frequencies, how loud should one talk into it or how close one's mouth should
be to the microphone, does it transmit lower frequencies (male voice) better than
higher frequencies (female voice), and external influences once the waves are in the air, like wind,
position of the student with respect to the PA system, temperature of the air...

FAQ: Sound waves and frequency problem

What are sound waves?

Sound waves are a type of mechanical wave that travel through a medium, such as air, and carry energy from one place to another. They are created when an object vibrates and cause the particles in the medium to vibrate, creating a series of compressions and rarefactions.

How is frequency related to sound waves?

Frequency is the number of waves that pass a certain point in a given amount of time. In the context of sound waves, frequency refers to the number of compressions and rarefactions that occur in one second. Higher frequencies produce higher pitched sounds, while lower frequencies produce lower pitched sounds.

What is the relationship between frequency and wavelength in sound waves?

Wavelength is the distance between two consecutive points on a wave that are in phase, such as two compressions or two rarefactions. In sound waves, the wavelength is inversely proportional to frequency. This means that as frequency increases, wavelength decreases and vice versa.

How do we measure the frequency of a sound wave?

The frequency of a sound wave is measured in hertz (Hz), which is equal to one cycle per second. This can be measured using a device called a frequency meter or by counting the number of waves that pass a specific point in one second.

Why is frequency important in understanding sound waves?

Frequency is important because it determines the pitch of a sound. Different frequencies result in different pitches, which are perceived by our ears. In addition, frequency can also affect the quality and timbre of a sound, making it an important factor in understanding and analyzing sound waves.
