What else can I help you with?
Is noise louder on the top floor or first floor?
Noise is typically louder on the first floor since it is closer to ground-level activities like street traffic and pedestrians. The top floor may have less external noise but more internal noise from neighbors above.
What food is at the top of the food chain with the highest level of toxic chemicals?
Humans.
What is the noise level distance formula used to calculate the distance between two points based on their respective noise levels?
The noise level distance formula calculates the distance between two points based on their noise levels. It is typically represented as: Distance ((Noise level 1 - Noise level 2)2).
Is ultrasonic noise harmful to humans and the environment?
Ultrasonic noise can be harmful to humans and the environment. Excessive exposure to ultrasonic noise can cause hearing damage and other health issues in humans. In the environment, ultrasonic noise can disrupt wildlife and ecosystems, affecting their behavior and communication.
What is the sound level of the noise measured at 42 dB?
The sound level of the noise measured at 42 dB is considered moderate and is similar to the noise level of a quiet library.
How can I use a Johnson noise calculator to determine the level of noise in a circuit?
To determine the level of noise in a circuit using a Johnson noise calculator, you need to input the resistance and temperature of the circuit into the calculator. The calculator will then provide you with the Johnson noise voltage, which represents the level of noise in the circuit.
Is ultrasonic noise harmless to humans and the environment?
Ultrasonic noise can be harmful to humans and the environment. Excessive exposure to ultrasonic noise can cause hearing damage and stress in humans, and can also disrupt wildlife and marine life. It is important to limit exposure to ultrasonic noise to protect both human health and the environment.
How do sharks and humans get along?
The make a noise
What is the decibel noise level of a concrete breaker?
The decibel noise level of a concrete breaker is at around 111 to 113. This can vary depending on what concrete breaker one is using, and might have a different noise level.
What level do humans occupy on an ecological pyramid?
Humans occupy the highest trophic level in an ecological pyramid, known as the tertiary consumers. This means they are at the top of the food chain and primarily feed on organisms from lower trophic levels.
What is a noise level of 65 decibels measured for?
A noise level of 65 decibels is equivalent to the sound of a normal conversation or background music in a restaurant. It is also the recommended noise level for a comfortable working environment.
How do you measure the noise of a fan?
The noise of a fan can be measured in decibels using a sound pressure level meter. Knowing the level of noise allows people to classify as pollution or conducive.
