What does Hipp strategy of analysis stand for?

(B) How I can use HIPP (Historical Context, Intended Audience, Purpose, Point of View) to further support my argument? Use as much specific, outside information (SOI) as you can in making your argument.

What does the H in Hipp stand for?

of the following: historical context, intended. audience, purpose, and/or point of view (HIPP-)

What does Leq stand for in math?

less than or equal

How do you calculate Leq in Excel?

Here’s a 6 Step Guide for Calculating the “Average” Noise Level

1. Put the individual 1 second samples into column A starting at row 5.
2. In the second column, divide each value by 10.
3. Now anti-log the value from Step 2.
4. Add together all of the values in column C.
5. We now need to divide this total by the number of samples.

What is dB a leq?

LAeq is the A-weighted Leq sound level. LAeq,T is the A-weighted Leq sound level, measured over a specified period of time (T) Most community and industrial noise measurements are A-weighted so the LAeq descriptor is widely used.

What does LEPd stand for in noise?

LEPd (formerly LEX) is one of the most widely used measures of noise exposure, and it depends not only on the sound pressure level but also on the duration of the noise exposure. It is the measure of noise exposure used in the ‘Noise at Work Regulations 2005’ that is currently in force in the UK.

What is LA90 noise level?

The LA90 is the noise level exceeded for 90% of the measurement period. It is generally used to quantify the background noise level, the underlying level of noise which is present even during the quieter parts of the measurement period.

What is LMAX in noise?

The LMAX, or Maximum Sound Level, descriptor is the highest sound level measured during a single noise event (such as a vehicle pass by), in which the sound level changes value as time goes on.

What is the maximum sound level?

Eighty-five decibels is considered the highest safe exposure level up to a maximum of eight hours. The permissible time for safe listening decreases as sound levels increase. For example, a sound as high as 100 dB – the level produced by a subway train – can be safely listened to for only 15 minutes each day.

How far away can you hear 100 dB?

The effective distance of a 100 dB(A) sounder in a very noisy environment is 1.8m, the distance for a 120 dB(A) sounder is approx 18m (10 times the distance).

What is the 3dB rule?

3dB rule when measuring noise at work When you measure noise levels with a noise meter, you measure the intensity of noise in units called decibels, expressed as dB(A). It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value.

How far away can 80 dB be heard?

15 meters
