# Why are some sounds louder than others?

Sounds can be louder than others due to differences in their intensity or amplitude. Intensity is the amount of energy transmitted through the sound waves, with higher intensity resulting in a louder sound. Additionally, factors such as distance from the source of the sound and the medium through which the sound is traveling can also impact perceived loudness.

# What type of wave is sound waves?

sound waves are compression waves, or longitudinal waves. sounds that we hear are actually just compressions and rarefactions of air particles, meaning the air particles move closer together for a time period then spread apart farther then they normally would(a rarefaction)

# What is pitch of sound?

The pitch of sound refers to how high or low a sound is perceived. It is determined by the frequency of the sound waves, with higher frequencies producing higher pitched sounds and lower frequencies producing lower pitched sounds.

# What is the similarity between echoes of sound and images in a mirror?

Both echoes of sound and images in a mirror are reflections or reproductions of the original source. They are created through the phenomenon of reflection, where the waves of sound or light bounce off a surface and return back to the observer.

# A sound wave has compressions that are very close to each other What is true about this sound wave?

The frequency of this sound wave is very near constant.

# How does the pitch change when the balloon is tighter?

When a balloon is tighter, it produces a higher pitch because the increased tension in the balloon's surface causes it to vibrate at a faster rate. This faster vibration results in a higher frequency of sound waves being produced, which we perceive as a higher pitch.

# The sound of a bullfrog attracts a mate How much quieter is the sound if the mate is 4 times further away if the sound follows the inverse square law?

If the mate is 4 times further away, the sound will be 16 times quieter based on the inverse square law. This is because sound intensity decreases proportional to the square of the distance from the source.

# When did television sets get sound?

Television sets began incorporating sound in the late 1920s and early 1930s. The transition from silent to sound television was gradual, with the first synchronized sound broadcasts being experimented with in the late 1920s. By the 1930s, most television sets were equipped with sound capabilities.

# Symbol amplitude?

Symbol amplitude refers to the magnitude or strength of a symbol in a communication system. It is the intensity of the signal representing a specific symbol, which can impact the signal-to-noise ratio and the quality of the communication. In digital communication, symbol amplitude is crucial for accurate symbol detection and decoding.

# The sound wave is directed towards a cliff that is 680 meters away from the source of the sound An echo wave is heard 4 seconds after the wave is produced What is the period of the sound wave?

The time it takes for the sound to travel to the cliff and back as an echo is 4 seconds. Since the sound wave travels twice the distance to the cliff and back, the total distance traveled is 2 × 680 = 1360 meters. Using the formula speed = distance/time, we can calculate the speed of sound. The period of the sound wave is the time it takes for one complete cycle, which in this case is the time it takes for the sound to travel to the cliff and back, which we found to be 4 seconds.

# How can you prevent echoes in auditoriums?

To prevent echoes in auditoriums, you can use sound-absorbing materials such as acoustic panels or curtains to reduce sound reflections. Additionally, placing carpeting or other soft furnishings can help absorb sound. Properly positioning speakers and microphones can also help minimize echoes.

# What is sonication?

Sonication is a technique that uses sound waves to agitate particles in a sample, typically to break down cell walls or disrupt molecular structures. It is commonly used in laboratories for tasks such as cell lysis, nanoparticle dispersion, and sample preparation.

# What is the frequency of a hand clap?

The frequency of a typical hand clap is around 250 to 500 Hz. This means that the clap creates 250 to 500 sound waves per second.

# When sound wave refracted from air to water what will remain unchanged?

The frequency of the sound wave will remain unchanged when it refracts from air to water.

# Dba sound level vacuum?

The sound level of a vacuum cleaner generally ranges from 70 to 80 decibels (dB). It's advisable to look for models with noise-reducing features if a quieter operation is preferred.

# The frequency of a sound wave determines?

The frequency of a sound wave determines the pitch of the sound, with higher frequencies corresponding to higher pitches and lower frequencies corresponding to lower pitches.

# Sound travels in what kind of wave?

Sound travels in longitudinal waves, which means that the particles of the medium move in the same direction as the wave is propagating. This is in contrast to transverse waves where the particles move perpendicular to the wave's direction.

# What is the Microwave disadvantages?

Microwaves can lead to uneven heating, resulting in some parts of the food being overcooked while others remain cold. They can also cause a loss of nutrients in certain foods due to the high heat levels and fast cooking times. Additionally, microwaves are not suitable for all types of cooking, such as those that require browning or crisping.

# How do Airplanes use Sonar waves?

Airplanes do not use sonar waves. Sonar is a technology primarily used underwater to detect objects or measure distances by emitting sound waves. Airplanes generally use radar technology to detect and track objects in the sky.

# The lowest frequecy note of an organ is 16.4 Hz. What is the length of the shortest open organ pipe that will resonate at this frequency?

The formula to calculate the length of the shortest open organ pipe that will resonate at a specific frequency is: Length = (v / 4f), where v is the speed of sound in air (approximately 343 m/s). Plugging in the values, the length of the shortest pipe would be around 5.22 meters.

# What is sound pitch?

Sound pitch refers to how high or low a sound is perceived by the human ear. It is determined by the frequency of the sound wave, with higher frequencies corresponding to higher pitches and lower frequencies to lower pitches. Pitch is an important characteristic of sound that helps us distinguish between different types of sounds.

# A high frequency sound will be heard as?

A high frequency sound will be heard as a sharp, piercing noise to the human ear. This type of sound typically contains rapid vibrations and has a high pitch.

# How do sound waves move?

Sound waves are vibrations that travel through a medium, such as air, water, or solids, by causing particles in the medium to bump into each other. This transfers energy from one particle to the next, allowing the wave to propagate through the medium. The particles in the medium oscillate back and forth in the direction of the wave, creating a compressional wave that we perceive as sound.
