Given:
– Speed of the sound wave = 339 m/s
– Wavelength = 1.5 cm (Converted to meters: 1.5 cm = 0.015 m
Using the formula Speed = Frequency x Wavelength, rearranged to solve for frequency:
Frequency = (Speed of wave)/(Wavelength)
Substituting the values:
Frequency = (339 m/s)/(0.015 m)
Frequency ≈ 22,600 Hz
Therefore, the frequency of the sound wave is approximately 22,600 Hz.
Regarding audibility, the human audible range typically spans from 20 Hz to 20,000 Hz. The calculated frequency of 22,600 Hz falls beyond this range. Most people would likely be unable to hear a sound with this frequency, though younger individuals may sometimes perceive slightly higher frequencies.

Reverberation refers to the persistence of sound in a space even after the original sound source stops emitting sound. It occurs due to multiple reflections of sound waves off surfaces within an enclosed area. These reflections cause the sound to linger, creating an echo-like effect that prolongs the decay of the sound.
Causes of Reverberation:
1. Surface Reflections: Sound waves bouncing off hard surfaces like walls, ceilings, and floors.
2. Room Size and Construction: Large, open spaces with few sound-absorbing materials tend to create more pronounced reverberation.
Ways to Reduce Reverberation:
1. Acoustic Treatment: Use sound-absorbing materials like acoustic foam, fabric-covered panels, or perforated panels strategically placed on walls to absorb sound waves and minimize reflection.
2. Soft Furnishings: Incorporate carpets, drapes, curtains, or upholstered furniture, as they help absorb sound and reduce excessive reflection.
3. Diffusers: Install diffusers on walls or ceilings to scatter sound waves, preventing direct reflections and creating a more diffuse sound environment.
4. Sound-Absorbing Elements: Utilize objects designed for sound absorption, such as bookshelves, plants, or specialized acoustic elements, strategically positioned in the room.
5. Ceiling Treatments: Use suspended baffles or acoustic clouds on ceilings to absorb sound and mitigate reverberation.
6. Room Design Considerations: Employ irregular surfaces or shapes in the room design to break up sound waves and diminish direct reflections.
Implementing these methods effectively controls and reduces reverberation, enhancing speech clarity, improving audio quality, and decreasing unwanted noise levels in a space.

Loudness denotes the subjective perception of the intensity or strength of a sound as interpreted by the human ear. It describes the sensation of how soft or loud a sound appears to be.
Key Factors Impacting Loudness:
1. Amplitude or Intensity: Loudness primarily hinges on the amplitude or intensity of the sound wave. A higher amplitude corresponds to a more powerful sound and is perceived as louder. Increased amplitude equates to more energetic vibrations, which our ears interpret as louder noises.
2. Frequency: While amplitude is the key, the frequency of the sound wave also plays a role. Certain frequencies might seem louder than others at the same amplitude. The human ear is particularly sensitive to frequencies within the range of human speech (approximately 1 kHz to 4 kHz).
3. Distance from Source: Sound waves disperse and lose intensity with distance from the source. As a result, the perceived loudness diminishes when one moves away from the sound source.
4. Environmental Factors: The surroundings influence how sound waves propagate. Enclosed spaces may reflect sound waves, potentially enhancing the perceived loudness due to reverberation or amplification.
5. Ear Sensitivity: Individual differences in hearing sensitivity, influenced by factors like age, exposure to loud noises, and overall ear health, can affect one’s perception of sound intensity.
In essence, loudness represents the subjective perception of sound intensity by the human ear. While primarily contingent on amplitude, other factors such as frequency, distance, environmental conditions, and individual hearing characteristics collectively contribute to our perception of loudness.

Ultrasonic Cleaning Process:
1. Equipment Setup: Ultrasonic cleaning involves a tank filled with a cleaning solution, typically water or solvent, where an ultrasonic transducer is immersed.
2. Ultrasonic Transducer Action: The transducer generates high-frequency sound waves (above the range of human hearing, around 20 kHz to several hundred kHz) and emits them into the cleaning solution.
3. Cavitation: The high-frequency sound waves create microscopic bubbles in the solution, a process called cavitation. These bubbles rapidly expand and collapse due to the alternating pressure from the sound waves passing through the liquid.
4. Cleaning Action: During the collapse phase (implosion) of these bubbles, intense scrubbing and agitation occur in the solution. This phenomenon generates microjets and vacuum bubbles that penetrate and dislodge dirt, grease, or contaminants from the surfaces of objects submerged in the solution.
Applications of Ultrasonic Cleaning:
– Industrial Use: In manufacturing, automotive, electronics, and healthcare industries for cleaning components, parts, machinery, and instruments.
– Jewelry and Watch Cleaning: Effective in removing dirt from intricate parts of jewelry, watches, and delicate items.
– Medical and Dental Equipment: Used to clean dental instruments, surgical tools, and medical equipment to ensure sterilization.

By analyzing the time taken for wave return and knowing the material’s sound speed, the equipment calculates defect distances or depths within the metal.
b. Through-Transmission Technique: One transducer emits waves while another on the opposite side receives them. Any changes in the received signals, such as attenuation or absorption, indicate the presence of defects within the metal block.
4. Analysis and Interpretation: Skilled technicians interpret the ultrasonic data to identify, characterize, and locate defects within the metal. They analyze signals to determine the presence, size, shape, and location of defects, such as cracks, inclusions, voids, or laminations.
Types of Detected Defects:
– Cracks: Surface or subsurface disruptions affecting material continuity.
– Inclusions: Foreign particles embedded in the metal.
– Voids or Porosity: Empty spaces or air pockets within the material.
– Laminations: Layers of material not well bonded together.
Ultrasonic testing is vital in industries like aerospace, manufacturing, and engineering. It ensures structural integrity by identifying defects before they lead to potential failures or malfunctions in metal components. This non-destructive method helps maintain quality and reliability in various metal-based applications.
