WHY CAN YOU HEAR THE OCEAN WHEN HOLDING A SEASHELL TO YOUR EAR?

Do you remember trying this as a kid - Holding one of the seashells you grabbed as a souvenir up to your ear? It seems like no matter how far away from the ocean you are, you can still hold a seashell up to your ear and hear the roar of the waves rolling onto the shore. The best shells for producing this sound are the large, spiral conch shells.

Some people have suggested that the sound you hear from the seashell is the echoing of your blood rushing through the blood vessels of your ear. That is not the case. If that were true, then the sound would intensify after exercising, since your blood races faster after exercising. However, the sound is the same even after exercising.

Others say that the whooshing sound inside the shell is generated by air flowing through the shell - air flowing through the shell and out creates a noise. You'll notice that the sound is louder when you lift the shell slightly away from your ear than it is when the shell is right against your head. However, this theory doesn't hold true in a soundproof room. In a soundproof room, there is still air, but when you hold the seashell to your ear, there's no sound.

The most likely explanation for the wave-like noise is ambient noise from around you. The seashell that you are holding just slightly above your ear captures this noise, which resonates inside the shell. The size and shape of the shell therefore has some effect on the sound you hear. Different shells sound different because different shells accentuate different frequencies. You don't even need the seashell to hear the noise. You can produce the same "ocean" sound using an empty cup or even by cupping your hand over your ear. Go ahead and try it and vary the distance at which you place the cup near your ear. The level of the sound will vary depending on the angle and distance the cup is from your ear.

Noise from outside the shell also can change the intensity of the sound you hear inside the shell. You can look at the shell as a resonating chamber. When sound from outside enters the shell, it bounces around, thus creating an audible noise. So, the louder the environment you are in, the louder the ocean-like sound will be.

SHOPPING

Shopping is the examining of goods or services from retailers with the intent to purchase at that time. Shopping is an activity of selection and/or purchase. In some contexts it is considered a leisure activity as well as an economic one.

To many, shopping is considered a recreational and diversional activity in which one visits a variety of stores in search of a suitable product to purchase. "Window shopping" is an activity that shoppers engage in by browsing shops with no intent to purchase, possibly just to pass the time between other activities, or to plan a later purchase.

More recently compulsive shopping is recognised as an addiction. Also referred as shopping addiction, "shopaholism" or formally oniomania, these shoppers have an impulsive uncontrollable urge to shop.

Shopping hubs

A larger commercial zone can be found in many cities, downtowns or Arab city souks. Shopping hubs, or shopping centers, are collection of stores; that is a grouping of several businesses. Typical examples include shopping malls, town squares, flea markets and bazaars.

Stores

Shops are divided into multiple categories of stores which sell a selected set of goods or services. Usually they are tiered by target demographics based on the disposable income of the shopper. They can be tiered from cheap to pricey.

Many shops are part of a shopping chain that carry the same trademark (company name) and logo using the same branding, same presentation, and sell the same products but in different locations.

Various types of retail stores that specialise in the selling of goods related to a theme include bookstores, boutiques, candy shops, liquor stores, gift shops, hardware stores, hobby stores, pet stores, pharmacies, sex shops and supermarkets.

Other stores such as big-box stores, hypermarkets, convenience stores, department stores, general stores, dollar stores sell a wider variety of products not horizontally related to each other.
